Configuring Node Fault Detection - HP MSR2000 Configuration Manual

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:
Step
1. Enter system view.
2. Enter MPLS TE view.
Enable the auto FRR function
3.
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.) Configure 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:

Remarks
N/A
N/A
By default, the auto FRR function 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 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.
