Hi All,
Multihop BFD (RFC 5883) packets are sent over UDP/IP. The encapsulation
used is identical to single hop BFD (RFC 5881) except that the UDP
destination port is set to 4784.
Now, suppose on the ingress node there is no IP/LFA backup path for the
destination address tracked by multihop BFD,
ecision of the BFD packet may not be taken by the network

S-BFD seems to the most appropriate mechanism that the head-end of a SR-TE
tunnel can use to detect failure in the absence of local protection in one
of the transit nodes..
Do we have any interop report for S-BFD? Or at least known
implementations/vendors that support S-BFD? I know Cisco IOS XR su
