RSVP configuration examples
Establishing an MPLS TE tunnel with RSVP-TE
Network requirements
Router A, Router B, Router C, and Router D run IS-IS and all of them are Layer 2 routers.
Use RSVP-TE to create an MPLS TE tunnel from Router A to Router D. The MPLS TE tunnel requires a
bandwidth of 2000 kbps.
The maximum bandwidth of the link that the tunnel traverses is 10000 kbps and the maximum reservable
bandwidth of the link is 5000 kbps.

Configuration procedure
1. Configure IP addresses and masks for interfaces. (Details not shown.)
2. Configure IS-IS to advertise interface addresses, including the loopback interface address:
# Configure Router A.
