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
