RSVP-TE GR configuration example
Network requirements
Router A, Router B and Router 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 Router A to Router C.
Router A, Router B and Router 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 27. (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 Router A.
<RouterA> system-view
[RouterA] mpls lsr-id 1.1.1.9
[RouterA] mpls
[RouterA-mpls] mpls te
[RouterA-mpls] mpls rsvp-te
[RouterA-mpls] mpls rsvp-te hello
[RouterA-mpls] interface giabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] mpls
[RouterA-GigabitEthernet2/1/1] mpls te
[RouterA-GigabitEthernet2/1/1] mpls rsvp-te
[RouterA-GigabitEthernet2/1/1] mpls rsvp-te hello
[RouterA-GigabitEthernet2/1/1] quit
# Configure Router B.
<RouterB> system-view
[RouterB] mpls lsr-id 2.2.2.9
[RouterB] mpls
[RouterB-mpls] mpls te
[RouterB-mpls] mpls rsvp-te
