Step
6. Enter interface view of the
output interface of a primary
CRLSP.
7. Specify a bypass tunnel for
the protected interface.

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.
An automatically created bypass tunnel can protect multiple primary CRLSPs. A bypass tunnel is
unused when the bypass tunnel is not bound to any primary CRLSP. When a bypass tunnel is
unused for the period of time configured by the timers removal unused command, MPLS TE
removes the bypass tunnel.
To configure auto FRR on the PLR:
Step
1. Enter system view.
2. Enter MPLS TE view.
3. Enable the auto FRR feature
globally.
4. Specify an interface number
range for the automatically
created bypass tunnels.
5. (Optional.) Configure the
PLR to create only
link-protection bypass
tunnels.
6. (Optional.) Set a removal
timer for unused bypass
tunnels.
7. (Optional.) Return to system
view.
8. (Optional.) Enter interface
view.
9. (Optional.) Disable the auto
FRR feature on the interface.

By default, no bypass tunnel is
specified for an interface.
Remarks
N/A
N/A
By default, the auto FRR feature is
disabled globally.
By default, no interface number
range is specified, and the PLR
cannot set up a bypass tunnel
automatically.
By default, the PLR automatically
creates both a link-protection and
a node-protection bypass tunnel
for each of its primary CRLSPs.
Execution of this command
deletes all existing
node-protection bypass tunnels
automatically created for MPLS
TE auto FRR.
By default, a bypass tunnel is
removed after it is unused for
3600 seconds.
N/A
N/A
By default, the auto FRR feature is
enabled on all RSVP-enabled
interfaces after it is enabled
globally.
Execution of this command
deletes all existing bypass tunnels
automatically created on the
interface for MPLS TE auto FRR.
