Configuring Node Protection; Configuring The Frr Polling Timer - HP 10500 SERIES Configuration Manual

Step
7. Enter interface view of the
outgoing interface of the
protected LSP.
8. Bind the bypass tunnel with
the protected interface.

Configuring node protection

To use FRR for node protection, perform the tasks in this section on the PLR and the protected node. If you
only need to protect links, skip this section.
To configure node protection:
Step
1. Enter system view.
2. Enter MPLS view.
3. Enable RSVP hello extension on current
node.
4. Return to system view.
5. Enter the view of the interface directly
connected to the protected node or PLR.
6. Enable RSVP hello extension on the
interface.
NOTE:
RSVP hello extension is configured to detect node failures caused by problems such as signaling error
other than failures caused by link failures.

Configuring the FRR polling timer

The protection provided by FRR is temporary. Once a protected LSP becomes available again or a new
LSP is established, traffic is switched to the protected or new LSP. After this switchover, the PLR polls
available bypass tunnels for the best one at the regular interval specified by the FRR polling timer:
To configure the FRR polling timer:
Step
1. Enter system view of the PLR
node.
2. Enter MPLS view.
3. Configure the FRR polling
timer.
