4000 Router Series MPLS Configuration Guide

10. On the ingress node of the MPLS TE tunnel, configure RSVP-TE to establish a CRLSP based on the

tunnel constraints and link TE attributes.

11. On the ingress node of the MPLS TE tunnel, configure static routing or PBR to direct traffic to the

MPLS TE tunnel.

You can also configure other MPLS TE functions such as the DS-TE and FRR as needed.

To configure MPLS TE, perform the following tasks:

Tasks at a

lance

(Required.) Enabling MPLS TE

(Required.) Configuring a tunnel interface

(Optional.) Configuring DS-TE

(Required.) Perform at least one of the following tasks to configure an MPLS TE tunnel:

• Configuring an MPLS TE tunnel to use a static CRLSP

• Configuring an MPLS TE tunnel to use a dynamic CRLSP

(Required.) Perform either task to configure traffic forwarding:

• Configuring static routing to direct traffic to an MPLS TE tunnel

• Configuring PBR to direct traffic to an MPLS TE tunnel

(Optional.) Configuring a bidirectional MPLS TE tunnel

(Optional.) Configuring CRLSP backup

Only MPLS TE tunnels established by RSVP-TE support this configuration.

(Optional.) Configuring MPLS TE FRR

Only MPLS TE tunnels established by RSVP-TE support this configuration.

Enabling MPLS TE

Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.

Before you enable MPLS TE, complete the following tasks:

• Configure static routing or IGP to make sure all LSRs can reach each other.

• Configure basic MPLS. For information about basic MPLS configurations, see "Configuring basic

MPLS."
