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 command system vrrp show at DUT1 and check if output contains the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 MASTER yes no 0:00:00 none
Step 4: Run command system vrrp show at DUT0 and check if output does not contain the following tokens:
MASTERShow 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
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:

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 command system vrrp show at DUT1 and check if output contains the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 MASTER yes no 0:00:01 none
Step 4: Run command system vrrp show at DUT0 and check if output does not contain the following tokens:

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
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:

-------------------------------------------------------------------------------- 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
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:

Test GARP Master Repeat Global
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 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-repeat 3
Step 3: Run command system vrrp show at DUT1 and check if output contains the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 MASTER yes no 0:00:00 none
Step 4: Run command system vrrp show at DUT0 and check if output does not contain the following tokens:
MASTERShow 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
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:

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
GARP timestamps (in seconds with two decimals):

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$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0' set system vrrp global-parameters garp master-refresh 5
Step 3: Run command system vrrp show at DUT1 and check if output contains the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 MASTER yes no 0:00:00 none
Step 4: Run command system vrrp show at DUT0 and check if output does not contain the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 BACKUP yes no 0:00:03 none
Note
In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).
Step 5: Modify the following configuration lines in DUT1 :
set interfaces ethernet eth0 disable
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:
admin@DUT0$ interfaces ethernet eth0 show detailedShow 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
GARP timestamps (in seconds with two decimals):

Test GARP Master Refresh Repeat
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$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Run command system vrrp show at DUT1 and check if output contains the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 MASTER yes no 0:00:01 none
Step 4: Run command system vrrp show at DUT0 and check if output does not contain the following tokens:
MASTERShow output
-------------------------------------------------------------------------------- Interface Group State RFC Compliant Addr Owner Last Transition Sync Group -------------------------------------------------------------------------------- eth0 1 BACKUP yes no 0:00:03 none
Note
In order to force DUT0 to become MASTER, interface eth0 in DUT1 must be disabled (GARP packets are sent after a device becomes MASTER).
Step 5: Modify the following configuration lines in DUT1 :
set interfaces ethernet eth0 disable
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:
admin@DUT0$ interfaces ethernet eth0 show detailedShow output

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
Note
Get DUT0’s MAC address to check that packets are sent from DUT0 (IP address is not showed).
Step 6: Get the MAC address of the eth0 interface:

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
