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.
Configuration procedure
To create an MPLS TE tunnel over a CR-LSP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter the interface view of an
MPLS TE tunnel.
interface tunnel tunnel-number N/A
3. Configure the tunnel to use
static CR-LSP.
mpls te signal-protocol static N/A
4. Submit the current tunnel
configuration.
mpls te commit N/A
5. Exit to system view. quit N/A
