Step
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 function on the
interface.
Configuring node fault detection
Perform this task to configure the RSVP hello mechanism or BFD on the PLR and the protected node
to detect the node faults caused by signaling protocol faults. FRR does not need to use the RSVP
hello mechanism or BFD to detect the node faults caused by the link faults between the PLR and the
protected node.
You do not need to perform this task for FRR link protection.
To configure node fault detection:
Step
1.
Enter system view.
2.
Enter interface view.
3.
Configure node fault
detection.

Remarks
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 function
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.
Remarks
N/A
On the PLR, enter the view of
the interface connected to
the protected node.
On the protected node, enter
the view of the interface
connected to the PLR.
By default, RSVP hello
extension is disabled, and
BFD is not configured.
For more information about
the rsvp hello enable
command and the rsvp bfd
enable command, see
"Configuring
RSVP."
