Inspecting An Mpls Te Tunnel - HP 12500 Series Configuration Manual

To configure node protection:
To do...
Enter system view
Enter MPLS view
Enable RSVP hello extension on
current node
Exit to system view
Enter the view of the interface
directly connected to the protected
node or PLR
Enable RSVP hello extension on the
interface
NOTE:
RSVP hello extension is configured to detect node failures caused by problems such as signaling error
other than failures caused by link failures.
Configuring the FRR polling timer
The protection provided by FRR is temporary. Once a protected LSP becomes available again or a new
LSP is established, traffic is switched to the protected or new LSP. After this switchover, the PLR polls
available bypass tunnels for the best one at the regular interval specified by the FRR polling timer:
To configure the FRR polling timer:
To do...
Enter system view of the PLR node
Enter MPLS view
Configure the FRR polling timer

Inspecting an MPLS TE tunnel

When an MPLS TE tunnel fails or affects data forwarding due to performance degradation, the control
plane cannot detect the fault or cannot do so in time. This brings difficulty to network maintenance. To
detect MPLS TE tunnel failures in time and locate the failed node, the switch provides the following
mechanisms:
MPLS LSP ping
•
• MPLS LSP tracert
BFD for an MPLS TE tunnel
•
Periodic tracert of an MPLS TE tunnel
