Configuring an MPLS TE tunnel to use a static CRLSP
To configure an MPLS TE tunnel to use a static CRLSP, perform the following tasks:
•
Establish the static CRLSP.
•
Specify the MPLS TE tunnel establishment mode as static.
•
Configure the MPLS TE tunnel to reference the static CRLSP.
Other configurations, such as tunnel constraints and IGP extension, are not needed.
To configure an MPLS TE tunnel to use a static CRLSP:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create a static CRLSP.
See "
." 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.
•
Establish the CRLSP by using the signaling protocol RSVP-TE.
You must configure the IGP TE extension to form a TEDB. Otherwise, the path is created based on IGP
routing rather than computed by CSPF.
