# Execute the display ip routing-table command on Switch A. The output shows a static route entry with

interface Tunnel 1 as the output interface.

Bidirectional MPLS TE tunnel configuration example

Network requirements

Switch A, Switch B, Switch C, and Switch D all run IS-IS.

Use RSVP-TE to establish a bidirectional MPLS TE tunnel between Switch A and Switch D.

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.

For more information, see "Establishing an MPLS TE tun

nel with RSVP-TE."

3. Configure an LSR ID, and enable MPLS, MPLS TE, and RSVP-TE on each switch, and configure

Switch A and Switch D to assign a non-null label to the penultimate hop:

# Configure Switch A.

<SwitchA> system-view

[SwitchA] mpls lsr-id 1.1.1.9
