Depending on the MPLS TE signaling protocol a tunnel uses, the basic capabilities you configured
in this section may be inadequate for the tunnel to work and you may need to make extra
configurations.

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 do not accept bandwidth constraints and 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:
z
Configure static routing or an IGP protocol to make sure that all LSRs are reachable.
