one-arm bfd session can not go up

one-arm bfd session can not go up

I configured one-arm bfd according to manual, however BFD session is down:

bfd LINK1 bind peer-IP 10.0.0.2 interface Eth-Trunk12.1 one-arm-echo

discriminator local 521

min-echo-rx-interval 1000

I tried with “Source-IP” – same issue BFD one-arm doesn’t work:

bfd LINK1 bind peer-IP 10.0.0.2 interface Eth-Trunk12.1 source-IP 10.0.0.1 one-arm-echo

discriminator local 521

   min-echo-rx-interval 1000
