RSVP-TE GR configuration example
Network requirements
Switch A, Switch B and Switch C are running IS-IS. All of them are Level-2 devices and support RSVP hello
extension.
Use RSVP-TE to create a TE tunnel from Switch A to Switch C.
Switch A, Switch B, and Switch C are RSVP-TE neighbors. Configure the RSVP-TE GR on the routers, so
each of them can provide GR helper support when another is GR restarting.

Configuration procedure
1. Configure IP addresses and masks for the interfaces according to Figure 33. (Details not shown.)
2. Enable IS-IS to advertise host routes with LSR IDs as destinations. (Details not shown.)
3. Configure basic MPLS TE, and enable RSVP-TE and RSVP hello extension:
# Configure Switch A.
