MPLS TE configuration task list

To configure an MPLS TE tunnel to use a static CRLSP, complete the following tasks:

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

2. Create a tunnel interface on the ingress node of the MPLS TE tunnel, and specify the tunnel

destination address—the address of the egress node.

3. Create a static CRLSP on each node that the MPLS TE tunnel traverses.

For information about creating a static CRLSP, see "Configuring a static CRLSP."

4. On the ingre

ss node of the MPLS TE tunnel, configure the tunnel interface to reference the created

static CRLSP.

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

tunnel.

To configure an MPLS TE tunnel to use a CRLSP dynamically established by RSVP-TE, complete the

following tasks:

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

For information about enabling RSVP, see "Configuring RSVP."

7. Create a tu

nnel interface on the ingress node of the MPLS TE tunnel, and specify the address of the

egress node as the tunnel destination address.

8. Configure an IGP on each node that the MPLS TE tunnel traverses.

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

path calculated by IGP.

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

tunnel.

You can also configure other MPLS TE functions such as bidirectional MPLS TE tunnel as needed.

To configure MPLS TE, perform the following tasks:
