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

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 system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

Check connectivity

Step 4: Ping IP address 192.168.1.2 from DUT0:

admin@DUT0$ ping 192.168.1.2 count 1 size 56 timeout 1

Show output

PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.243/0.243/0.243/0.000 ms

Step 5: Ping IP address 192.168.1.1 from DUT1:

admin@DUT1$ ping 192.168.1.1 count 1 size 56 timeout 1

Show output

PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.243/0.243/0.243/0.000 ms

Note

Check that they are each other’s neighbors

Step 6: Run command protocols ospf show neighbor at DUT0 and check if output matches the following regular expressions:

192.168.1.2

Show output

Note

Check that they are each other’s peers and that their status is up (the BFD session has beedn successfully established). Check that all configureed profile parameters are shown in DUT0

Step 8: Run command protocols bfd show peers at DUT0 and check if output matches the following regular expressions:
