Establishing A Crlsp By Using The Path Calculated By Pces; Establishing A Backup Crlsp By Using The Path Calculated By Pces; Configuring Pcep Session Parameters - HP FlexNetwork 10500 Series Configuration Manual

Establishing a CRLSP by using the path calculated by PCEs

Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Establish a CRLSP by
using the path calculated
by PCEs.
Establishing a backup CRLSP by using the path calculated
by PCEs
Perform this task to enable the specified PCEs to calculate a backup CRLSP for the PCC. When the
primary CRLSP fails, traffic is switched to the backup CRLSP to ensure continuous traffic forwarding.
To establish a backup CRLSP by using the path calculated by PCEs:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Enable tunnel backup
and specify the backup
mode.
4. Establish a backup
CRLSP by using the path
calculated by PCEs.

Configuring PCEP session parameters

Step
1. Enter system view.
2. Enter MPLS TE view.

By default, the automatically
calculated path is used to
establish a CRLSP.
After this command is
executed, the local device acts
as a PCC and establishes
PCEP sessions to the specified
PCEs. If you do not specify a
PCE, the local device
establishes PCEP sessions to
all discovered PCEs.
