Establishing An Mpls Te Tunnel By Using Rsvp-Te; Controlling Crlsp Path Selection - HP MSR2000 Configuration Manual

Step
2. Create an explicit path and
enter its view.
3. Enable the explicit path.
4. Add or modify a node in the
explicit path.
5. Return to system view.
6. Enter MPLS TE tunnel interface
view.
7. Configure the MPLS TE tunnel
interface to use the explicit
path, and specify a preference
value for the explicit path.

Establishing an MPLS TE tunnel by using RSVP-TE

Before you configure this task, you must use the rsvp command and the rsvp enable command to enable
RSVP on all nodes and interfaces that the MPLS TE tunnel traverses.
Perform this task on the ingress node of the MPLS TE tunnel.
To configure RSVP-TE to establish an MPLS TE tunnel:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Configure MPLS TE to use
RSVP-TE to establish the tunnel.
4. Specify an explicit path for the
MPLS TE tunnel, and specify
the path preference value.

Controlling CRLSP path selection

Before performing the configuration tasks in this section, be aware of each configuration objective and
its impact on your device.
MPLS TE uses CSPF to calculate a path according to the TEDB and constraints and sets up the CRLSP
through RSVP-TE. MPLS TE provides measures that affect the CSPF calculation. You can use these
measures to tune the path selection for CRLSP.

Remarks
By default, no explicit path exists
on the device.
By default, an explicit path is
enabled.
By default, an explicit path does
not include any node.
You can specify the include
keyword to have the CRLSP
traverse the specified node or the
exclude keyword to have the
CRLSP bypass the specified node.
