Automatic Derivation of remote discriminator for S-BFD session in SR-TE

You can use the automatically derived route discriminator for Seamless BFD (S-BFD) sessions on segment routing -- traffic engineering (SR-TE) paths. With this feature, you don't need to configure a remote discriminator in the S-FBD configuration on the ingress or transit device. Instead, the egress provider edge device will now accept an IP address as a local discriminator. To configure this feature, use the set protocols bfd sbfd local-discriminator-ip command. Additionally, you can now use a common sBFD template with the S-FBD configurations on multiple controller-provisioned SR-TE policies. In these sBFD sessions, Junos OS automaticallyderives the remote discriminator from the tunnel endpoint for matching SR-TE policies.
