200BBidirectional MPLS TE tunnel configuration example
412BNetwork requirements
Switch A, Switch B, Switch C, and Switch D all run IS-IS and they are all level-2 switches.
Use RSVP-TE to establish a bidirectional MPLS TE tunnel between Switch A and Switch D.

413BConfiguration 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.
For more information, see "
742HEstablishing an MPLS TE tunnel with RSVP-TE."
3. Configure an LSR ID, and enable MPLS, MPLS TE, and RSVP-TE on each switch. Configure
Switch A and Switch D to assign a non-null label to the penultimate hop:
# Configure Switch A.
