Configuring an RSVP CR-LSP and Specifying Bandwidth Values

Procedure

• Configure IGP TE.

  For detailed configurations, see Configuring IGP TE (IS-IS).

• Configure CSPF.

  For configuration details, see Configuration CSPF.

• Configure bandwidth values for an MPLS TE tunnel.

  Perform the following steps on the ingress of a tunnel:

  1. Run system-view

     The system view is displayed.

  2. Run interface tunnel interface-number

     The MPLS TE tunnel interface view is displayed.

  3. Run mpls te bandwidth { ct0 bw-value | ct1 bw-value | ct2 bw-value | ct3 bw-value | ct4 bw-value | ct5 bw-value | ct6 bw-value | ct7 bw-value }

     Single-CT information is specified.

  4. Run commit

     The configuration is committed.

  For the same node, the sum of CTi bandwidth values must not exceed the BCi bandwidth values (0 <= i <= 7). CTi can use bandwidth resources only of BCi.

  

  If the bandwidth required by the MPLS TE tunnel is higher than 28,630 kbit/s, the available bandwidth assigned to the tunnel may not be precise, but the tunnel can be established successfully.

• (Optional) Configure an explicit path.

  To limit the path over which an MPLS TE tunnel is established, perform the following steps on the ingress of the tunnel:

  1. Create an explicit path. For detailed configuration, see (Optional) Configuring an MPLS TE Explicit Path.
  2. Run quit

     Return to the system view.

  3. Run interface tunnel interface-number

     The MPLS TE tunnel interface view is displayed.

  4. Run mpls te path explicit-path path-name

     An explicit path is configured for the tunnel.

  5. Run commit

     The configuration is committed.
