Creating An Mpls Te Tunnel Over A Static Cr-Lsp; Configuration Prerequisites; Configuration Procedure - H3C S5500-HI Series Mpls Configuration Manual

Step
6. Enable interface MPLS TE.
7. Return to system view.
8. Create a tunnel interface and
enter its view.
9. Assign an IP address to the
tunnel interface.
10. Set the tunnel protocol to
MPLS TE.
11. Configure the destination
address of the tunnel.
12. Configure the tunnel ID of the
tunnel.
13. Submit the current tunnel
configuration.
For more information about tunnel interfaces, see Layer 3—IP Services Configuration Guide.

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.
To create an MPLS TE tunnel over a CR-LSP:
Step
1. Enter system view.
2. Enter the interface view
of an MPLS TE tunnel.
