Configuring Node Fault Detection; Setting The Optimal Bypass Tunnel Selection Interval - HP FlexNetwork 10500 Series Configuration Manual

Step
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.

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.

Setting the optimal bypass tunnel selection interval

If you have specified multiple bypass tunnels for a primary CRLSP, MPLS TE selects an optimal
bypass tunnel to protect the primary CRLSP. Sometimes, a bypass tunnel might become better than
the current optimal bypass tunnel because, for example, the reservable bandwidth changes.
Therefore, MPLS TE needs to poll the bypass tunnels periodically to update the optimal bypass
tunnel.
Perform this task on the PLR to set the interval for selecting an optimal bypass tunnel:
Command
timers removal unused seconds

mpls te auto-tunnel backup
disable
Command

•
(Method 1) Enable RSVP hello
extension on the interface:
rsvp hello enable
•
(Method 2) Enable BFD on the
interface:
rsvp bfd enable
102
Remarks
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.
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.

the rsvp hello enable
command and the rsvp bfd
enable command, see
