When configuring BFD multi-hop, some steps are required. 1: create the BFD template: bfd-template multi-hop bfd_template interval min-tx 1000 min-rx <number in ms> multiplier <number>

2: Configure BFD multi-hop map for each BFD test. The example below uses VRF but it can be ignored bfd map ipv4 vrf <DEST VRF> <DEST IP> vrf <SOURCE VRF> <SOURCE IP> <BFD TEMPLATE NAME - Step 1>

3: Enable BFD for the neighbour inside BGD router bgp 65321 address-family ipv4 vrf <SOURCE VRF> neighbor <DEST IP> fall-over bfd multi-hop exit-address-family
