Creating MPLS TE tunnel over 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. What you need to do is to 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 making the configuration, do the following:
•
Configure static routing or an IGP protocol to make sure that all LSRs are reachable.
•
Configure MPLS basic capabilities.
•
Configure MPLS TE basic capabilities.
