Establishing An Mpls Te Tunnel By Using Rsvp-Te; Controlling Crlsp Path Selection - HP FlexNetwork 10500 Series Configuration Manual

Step
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.
Configuring the metric type for path selection
Each MPLS TE link has two metrics: IGP metric and TE metric. By planning the two metrics, you can
select different tunnels for different classes of traffic. For example, use the IGP metric to represent a

Remarks
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.
