S-BFD support for SRv6 TE paths

You can enhance continuity checks for SRv6 traffic engineering (TE) paths by configuring Seamless BFD (S-BFD). S-BFD sessions monitor the state of SRv6 paths, ensuring that paths remain active only when S-BFD sessions are up.

You can configure S-BFD by using the sbfd configuration statement at the [edit protocols source-packet-routing source-routing-path tunnel primary path bfd-liveness-detection] hierarchy level. You can also use the destination-ipv6-local-host option for the sbfd statement to enforce the use of an IPv6 local host address for S-BFD responders that support only IPv6 local host addresses.
