Usage guidelines
After you execute the auto-tunnel backup command, and specify an interface number range for bypass
tunnels by using the tunnel-number command, the local device (the PLR) automatically sets up two
bypass tunnels for each of its primary CRLSPs: one for link protection and the other for node protection.
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.
Execution of the undo auto-tunnel backup command deletes all existing bypass tunnels automatically
created for MPLS TE auto FRR.

view.
