Seamless BFD for SR-TE
This chapter shows how to configure seamless bfd and how to use isis to advertise local-discriminators. Bidirectional Forwarding Detection (BFD) is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols.
Seamless Bidirectional Forwarding Detection (S-BFD), is a simplified mechanism for using BFD with a large proportion of negotiation aspects eliminated, thus providing benefits such as quick provisioning, as well as improved control and flexibility for network nodes initiating path monitoring. If SBFD session fails, S-BFD does not bring down the SR-TE session. SBFD also provides faster session bring up due to less control packets exchange. S-BFD does not help in bringing up SR-TE session quickly. The BFD state is only maintained at head end thereby reducing overhead.
Topology
In Figure :
• "L1" means ISIS routers in Level-1
• "L2" means ISIS routers in Level-2
• "L1/L2" means ISIS routers in both Level-1 and Level-2
You can configure a prefix SID on any router directly attached to that network prefix.
BFD for ISIS Segment Routing Topology
Note: You must ensure that prefix SIDs are unique globally.
Note: You can use the pure L1 or L2 routers throughout your SR domain.
Note: Redistribution from L1 to L2 and vice-versa is not supported for SR in this release.

In the forwarding tables above, the configured prefix SIDs are in the Out-Label column which is expected and is global across the topology. The swap happens in between nodes with this prefix SID and there is no local labelling.
Also verify the ILM and FTN tables.
