Usage guidelines
This feature enables the device to automatically set up two bypass tunnels for each primary CRLSP: one for link protection and the other for node protection. For the tunnels to be set up, you must also use the tunnel-number command to specify a tunnel interface number range.
Execution of the undo auto-tunnel backup command deletes all existing bypass tunnels automatically created for MPLS TE 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.
