4000 Router Series MPLS Configuration Guide

You must configure the IGP TE extension to form a TEDB. Otherwise, the path is created based on IGP

routing rather than computed by CSPF.

Configuration task list

To establish an MPLS TE tunnel by using a dynamic CRLSP, perform the following tasks:

Tasks at a

lance

(Required.) Configuring MPLS TE attributes for a link

(Required.) Configuring MPLS TE tunnel constraints

(Required.) Establishing an MPLS TE tunnel by using RSVP-TE

(Optional.) Controlling CRLSP path selection

(Optional.) Controlling MPLS TE tunnel setup

Configuring MPLS TE attributes for a link

MPLS TE attributes for a link include the maximum link bandwidth, the maximum reservable bandwidth,

and the link attribute.

Perform this task on each interface that the MPLS TE tunnel traverses.

To configure the link TE attributes:
