Configuring a Dynamic MPLS TE Tunnel

Configuring a Dynamic MPLS TE Tunnel

Dynamic MPLS TE tunnels are set up using RSVP-TE signaling and are changed according to network changes. On a large-scale network, dynamic MPLS TE tunnels reduce the burden of per-hop configuration. Configuring a dynamic MPLS TE tunnel is the basis for configuring advanced features of MPLS TE.

Pre-configuration Tasks

Before configuring a dynamic MPLS TE tunnel, complete the following tasks:

  • Configure an IGP to ensure reachable routes between nodes.

  • Configure an LSR ID for each node.

  • Enable MPLS globally on each node.

  • Enable MPLS on each interface of each node.

Configuration Procedure

Except that configuring link bandwidth, referencing the CR-LSP attribute template to set up a CR-LSP, and configuring tunnel constraints are optional, all the other configurations are mandatory.
