Configuration Procedure

ONFIGURATION
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 spanning 16 to 1023.
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.
■
Follow these steps to create an MPLS TE tunnel over a CR-LSP:
To do...
Enter system view
Enter the interface view of an MPLS
TE tunnel
Configure the tunnel to use static
CR-LSP
Submit the current tunnel
configuration
Exit to system view
Use the command...
