Test Profile

Description

Checks BFD profile in OSPF.

Scenario

Step 1: Set the following configuration in DUT0 :

set interfaces dummy dum0 address 10.0.0.1/24
set interfaces ethernet eth0 address 192.168.1.1/24
set interfaces ethernet eth0 ip ospf bfd
set interfaces ethernet eth0 ip ospf network point-to-point
set protocols bfd profile PFL detect-multiplier 5
set protocols bfd profile PFL echo-interval 60
set protocols bfd profile PFL echo-mode
set protocols bfd profile PFL passive-mode
set protocols bfd profile PFL receive-interval 400
set protocols bfd profile PFL transmit-interval 400
set protocols ospf area 0 network 10.0.0.0/24
set protocols ospf area 0 network 192.168.1.0/24
set protocols ospf parameters router-id 1.1.1.1

Step 2: Modify the following configuration lines in DUT0 :

set interfaces ethernet eth0 ip ospf bfd profile PFL

Step 3: Set the following configuration in DUT1 :

set interfaces dummy dum0 address 10.0.0.2/24
set interfaces ethernet eth0 address 192.168.1.2/24
set interfaces ethernet eth0 ip ospf bfd
set interfaces ethernet eth0 ip ospf network point-to-point
set protocols ospf area 0 network 10.0.0.0/24
set protocols ospf area 0 network 192.168.1.0/24
set protocols ospf parameters router-id 2.2.2.2
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Step 4: Ping IP address 192.168.1.2 from DUT0:
