Note
Check connectivity
Step 3: Ping IP address 3fff:10::200 from DUT0:
admin@DUT0$ ping 3fff:10::200 count 1 size 56 timeout 1Show output
PING 3fff:10::200(3fff:10::200) 56 data bytes 64 bytes from 3fff:10::200: icmp_seq=1 ttl=64 time=263 ms --- 3fff:10::200 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 262.719/262.719/262.719/0.000 ms
Step 4: Ping IP address 3fff:10::100 from DUT1:
admin@DUT1$ ping 3fff:10::100 count 1 size 56 timeout 1Show output
PING 3fff:10::100(3fff:10::100) 56 data bytes 64 bytes from 3fff:10::100: icmp_seq=1 ttl=64 time=0.201 ms --- 3fff:10::100 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.201/0.201/0.201/0.000 ms
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 configured profile parameters are shown in DUT0
Step 5: Run command protocols bfd show peers at DUT0 and check if output matches the following regular expressions:
3fff:10::200 Status: up Detect-multiplier: 5 Echo receive interval: disabled Echo transmission interval: disabled Passive mode Receive interval: 400ms Transmission interval: 400msShow output

Step 6: Run command protocols bfd show peers at DUT1 and check if output matches the following regular expressions:
3fff:10::100 Status: upShow output
