Creating an MPLS TE Tunnel over a static CR-LSP
Creating MPLS TE tunnels over static CR-LSPs does not involve configuration of tunnel constraints or the
issue of IGP TE extension or CSPF. Create a static CR-LSP and a TE tunnel using static signaling and then
associate them.
Despite its ease of configuration, the application of MPLS TE tunnels over static CR-LSPs is restricted
because they cannot dynamically adapt to network changes.
Static CR-LSPs are special static LSPs. They share the same constraints and use the same label space.
Configuration prerequisites
Before you perform the configuration, complete the following tasks:
•
Configure static routing or an IGP protocol to ensure all LSRs are reachable.
•
Configure basic MPLS.
•
Configure basic MPLS TE.
Configuration procedure
Do not configure the next hop address as a local public address when configuring the static CR-LSP on
the ingress or a transit node.
