Configuring an MPLS TE tunnel to use a static CRLSP

To configure an MPLS TE tunnel to use a static CRLSP, establish the static CRLSP, specify the MPLS TE

tunnel establishment mode as static, and configure the MPLS TE tunnel to reference the static CRLSP.

Other configurations, such as tunnel constraints, IGP extension and CSPF, are not needed.

To configure an MPLS TE tunnel to use a static CRLSP:

Ste

Command

Remarks

1. Enter system view.

system-view N/A

2. Create a static CRLSP.

See "Configuring a static CRLSP."

N/A

3. Enter MPLS TE tunnel interface

view.

interface tunnel tunnel-number

[ mode mpls-te ]

Execute this command on the

ingress node.

4. Specify the MPLS TE tunnel

establishment mode as static.

mpls te signaling static

By default, MPLS TE uses RSVP-TE

to establish a tunnel.

5. Apply the static CRLSP to the

tunnel interface.

mpls te static-cr-lsp lsp-name

By default, a tunnel does not

reference any static CRLSP.

Configuring an MPLS TE tunnel to use a dynamic

CRLSP

To configure an MPLS TE tunnel to use a CRLSP dynamically established by RSVP-TE, complete the

following tasks:

• Configure MPLS TE attributes for the links.

• Configure IGP TE extension to advertise link TE attributes, so as to generate a TEDB on each node.

• Configure tunnel constraints.

• Use the CSPF to calculate a preferred path based on the TEDB and tunnel constraints.

• Establish the CRLSP by using the signaling protocol RSVP-TE.
