Configuring Ps Attributes For The Protection Group - HP HPE FlexNetwork MSR Router Series Configuration Manual

Step
11. (Optional.) Specify a backup traffic
processing unit for the tunnel
bundle interface (distributed
devices in standalone
mode/centralized devices in IRF
mode).
12. (Optional.) Specify a backup traffic
processing unit for the tunnel
bundle interface (distributed
devices in IRF mode).
13. (Optional.) Restore the default
settings for the tunnel bundle
interface.
14. (Optional.) Bring up the tunnel
bundle interface.

Configuring PS attributes for the protection group

By default, when the working tunnel fails, traffic is immediately switched from the working tunnel to
the protection tunnel to avoid traffic interruption. When the working tunnel recovers, traffic is
immediately switched from the protection tunnel to the working tunnel. On an unstable network
where the working and protection tunnels are up and down frequently, immediate switchovers might
affect traffic forwarding and burden the device.
To resolve the problem, use the following methods:
•
Delay switching—After the working tunnel fails, traffic is switched to the protection tunnel
when the switching holdoff timer expires. Traffic is not switched to the protection tunnel if the
working tunnel recovers within the holdoff time.
•
Disable reverting—After the working tunnel recovers, the protection group continues to use
the protection tunnel as long as the protection group is operating correctly.
•
Delay reverting—After the working tunnel recovers, the wait timer starts. If the working tunnel
is still operating correctly when the wait time expires, traffic is switched from the protection
tunnel to the working tunnel.
To configure attributes for the protection group:
Step
1. Enter system view.
2. Enter the view of a tunnel
bundle interface in protection
switching mode.
3. Set the switching holdoff time
when a working tunnel failure
is detected.
4. Specify whether to switch
traffic from the protection
tunnel to the working tunnel
when the working tunnel
recovers, and the wait time
for the switchover.
5. Configure the protection
