Automatically setting up bypass tunnels
With auto FRR, if the PLR is the penultimate node of a primary CRLSP, the PLR does not create a
node-protection bypass tunnel for the primary CRLSP.
To configure auto FRR on the PLR:
1. Enter system view.

By default, the auto FRR function
is disabled globally.
4. Specify an interface number
range for the automatically
created bypass tunnels.
