BFD one-arm echo not working on S9303

Issue Description

The BFD configuration is below:

bfd 2 bind peer-ip  vpn-instance management interface Ethernet0/0/0 source-ip one-arm-echo
discriminator local 8000
detect-multiplier 10

I tested this setup with multiple devices on the other end (Huawei and Cisco) but the session kept flapping.

The root cause of this is issue configuring BFD on the management interface (Ethernet0/0/0). The management interface does not support the BFD feature.
To fix this i needed to change the interface used for BFD detection.
