Configuring Node Protection; Configuring The Frr Polling Timer - HP HSR6800 Configuration Manual

Step
8. Bind the bypass tunnel with
the protected interface.

Configuring node protection

To use FRR for node protection, perform the configuration 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. Exit 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.
