Examples for High Availability (VRRP) — GARP timers

Test GARP Interval

Description

This scenario checks that an OSDx device can use VRRP configuring the delay between GARP packets sent on an interface per VRRP group.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 garp interval 5
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:03         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed
Show output
----------------------------------------------------------------------------------------------------------------
Name  Idx           IP Address           Admin  Oper  Link  MTU   Vrf  Upper  Lower    Type        Phys addr
----------------------------------------------------------------------------------------------------------------
eth0  2    192.168.100.100/24            up     up    up    1500                     ethernet  de:ad:be:ef:6c:00
           192.168.10.1/32
           fe80::dcad:beff:feef:6c00/64

Test GARP Interval Global

Description

This scenario checks that an OSDx device can use VRRP configuring the delay between GARP packets sent on an interface globally.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system vrrp global-parameters garp interval 5

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:03         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed

Test GARP Master Delay

Description

This scenario checks that an OSDx device can use VRRP configuring the delay of the second set of garp packets sent after transitioning to master per VRRP group.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 garp master-delay 2
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:03         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed
Show output
----------------------------------------------------------------------------------------------------------------
Name  Idx           IP Address           Admin  Oper  Link  MTU   Vrf  Upper  Lower    Type        Phys addr
----------------------------------------------------------------------------------------------------------------
eth0  2    192.168.100.100/24            up     up    up    1500                     ethernet  de:ad:be:ef:6c:00
           192.168.10.1/32
           fe80::dcad:beff:feef:6c00/64

Test GARP Master Delay Global

Description

This scenario checks that an OSDx device can use VRRP configuring the delay of the second set of garp packets sent after transitioning to master globally.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system vrrp global-parameters garp master-delay 2

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:03         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed
Show output
----------------------------------------------------------------------------------------------------------------

Test GARP Master Repeat

Description

This scenario checks that an OSDx device can use VRRP configuring the number of garp packets to send at a time after transitioning to master per VRRP group.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 garp master-repeat 3
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:02         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed
Show output
----------------------------------------------------------------------------------------------------------------

Test GARP Master Refresh

Description

This scenario checks that an OSDx device can use VRRP configuring the minimum time interval for refreshing garp while master per VRRP group.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 garp master-refresh 5
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:02         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed
Show output
----------------------------------------------------------------------------------------------------------------
Name  Idx           IP Address           Admin  Oper  Link  MTU   Vrf  Upper  Lower    Type        Phys addr
----------------------------------------------------------------------------------------------------------------
eth0  2    192.168.100.100/24            up     up    up    1500                     ethernet  de:ad:be:ef:6c:00
           192.168.10.1/32
           fe80::dcad:beff:feef:6c00/64

Note

Two sets of GARP packets are sent in groups of five, by default, after transitioning to master. Since the master-refresh parameter configures the minimum time interval for refreshing garp while master, and not after transitioning to master, it affects the GARP packets sent by DUT0 after the first two sets of GARP packets.

Note

Test GARP Master Refresh Global

Description

This scenario checks that an OSDx device can use VRRP configuring the minimum time interval for refreshing garp while master globally.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system vrrp global-parameters garp master-refresh 5

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:02         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

Description

This scenario checks that an OSDx device can use VRRP configuring the number of garp packets to send at a time while master per VRRP group.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 garp master-refresh 5
set interfaces ethernet eth0 vrrp vrrp-group 1 garp master-refresh-repeat 3
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:02         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------

Note

Two sets of GARP packets are sent in groups of five, by default, after transitioning to master. Since the master-refresh-repeat parameter configures the number of garp packets to send at a time while master, and not after transitioning to master, it affects the GARP packets sent by DUT0 after the first two sets of GARP packets.

Number of packets sent at a time: 3

Test GARP Master Refresh Repeat Global

Description

This scenario checks that an OSDx device can use VRRP configuring the number of garp packets to send at a time while master globally.

Scenario

Step 1: Set the following configuration in DUT1 :

set interfaces ethernet eth0 address 192.168.100.101/24
set interfaces ethernet eth0 vrrp vrrp-group 1 preempt
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 200
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 2: Set the following configuration in DUT0 :

set interfaces ethernet eth0 address 192.168.100.100/24
set interfaces ethernet eth0 vrrp vrrp-group 1 priority 100
set interfaces ethernet eth0 vrrp vrrp-group 1 virtual-address 192.168.10.1
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system vrrp global-parameters garp master-refresh 5
set system vrrp global-parameters garp master-refresh-repeat 3

Step 3: Run the command system vrrp show on DUT1 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Step 4: Run the command system vrrp show on DUT0 and check whether the output does not contain the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
  eth0       1    BACKUP       yes           no          0:00:02         none

Note

In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).

Step 5: Modify the following configuration lines in DUT1 :

set interfaces ethernet eth0 disable

Step 6: Run the command system vrrp show on DUT0 and check whether the output contains the following tokens:

MASTER
Show output
--------------------------------------------------------------------------------
Interface  Group  State   RFC Compliant  Addr Owner  Last Transition  Sync Group
--------------------------------------------------------------------------------
eth0       1    MASTER       yes           no          0:00:01         none

Note

Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).

Step 7: Get the MAC address of the eth0 interface:

admin@DUT0$ interfaces ethernet eth0 show detailed

Note

Two sets of GARP packets are sent in groups of five, by default, after transitioning to master. Since the master-refresh-repeat parameter configures the number of garp packets to send at a time while master, and not after transitioning to master, it affects the GARP packets sent by DUT0 after the first two sets of GARP packets.

Number of packets sent at a time: 3
