Configuring the failed link timer
A CSPF failed link timer starts once a link goes down. If IGP removes or modifies the link before the
timer expires, CSPF will update information about the link in TEDB and stops the timer. If IGP does not
remove or modify the link before the timer expires, the state of the link in TEDB will change to up.
Follow these steps to configure failed link timer:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS view mpls ––
Configure the CSPF failed link
timer
mpls te cspf timer failed-link
timer-interval
Optional
The default is 10 seconds.
Configuring the link metric used for routing a tunnel
For an MPLS TE link, you may assign it a TE metric. This TE metric or the IGP metric of the link is
used for routing MPLS TE tunnels, depending on which metric type is specified.
Follow these steps to configure the link metric used for routing a tunnel:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS view mpls ––
Configure the link metric type used
for routing TE tunnels without

Assign a TE metric to the link mpls te metric value
Optional
If no TE metric is assigned to the
link, IGP metric is used as the TE
metric by default.
