Configuring An Mpls Te Tunnel To Use A Dynamic Crlsp; Configuration Task List - HP FlexNetwork 10500 Series Configuration Manual

•
Specify the MPLS TE tunnel establishment mode as static.
•
Configure the MPLS TE tunnel to use 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
1. Enter system view.
2. Create a static CRLSP.
3. Enter MPLS TE tunnel
interface view.
4. Specify the MPLS TE tunnel
establishment mode as
static.
5. Apply the static CRLSP to
the tunnel interface.
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, perform 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.

Execute this command on the

By default, MPLS TE uses
RSVP-TE to establish a tunnel.
By default, a tunnel does not use
any static CRLSP.
