Configuration procedure
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.
Specifying the link metric type for tunnel path calculation
Follow these steps to specify the metric type for tunnel path calculation:
To do… Use the command... Remarks
Enter system view system-view ––
Enter MPLS view mpls ––
Specify the metric type to use when
no metric type is explicitly
configured for a tunnel
mpls te path metric-type { igp | te }
Optional
TE metrics of links are used by
default.
Return to system view quit ––
Enter MPLS TE tunnel interface view interface tunnel tunnel-number ––
Specify the metric type to use for
path calculation of the current
tunnel
mpls te path metric-type { igp | te }
Optional
By default, no link metric type is
specified and the one specified in
MPLS view is used.
Submit current tunnel configuration mpls te commit Optional
Return to system view quit ––
Enter interface view of MPLS TE link
interface interface-type
interface-number
––
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.
NOTE:
If you do not configure the mpls te path metric-type command in MPLS TE tunnel interface view, the
configuration in MPLS view takes effect.
Configuring the traffic flow type of a tunnel
Follow these steps to configure the traffic flow type of a tunnel:
