Configuring Traffic Forwarding Tuning Parameters; Configuring The Failed Link Timer - HP 10500 SERIES Configuration Manual

Create a bi-directional MPLS TE tunnel and enable forwarding adjacency at both ends of the tunnel to
make forwarding adjacency take effect.
To configure a forwarding adjacency:
Step
1. Enter system view.
2. Enter MPLS TE tunnel interface
view.
3. Enable IGP to advertise the
route of the MPLS TE tunnel to
IGP neighbors.
4. Assign a metric to the MPLS TE
tunnel.
5. Submit
configuration.
6. Exit to system view.
7. Enter OSPF view.
8. Enable
adjacency.

Configuring traffic forwarding tuning parameters

In MPLS TE, you can configure traffic forwarding tuning parameters, such as the failed link timer and
flooding thresholds, to change paths that IP or MPLS traffic traverses or to define type of traffic that may
travel down a TE tunnel.
You must use the configurations described in this section in conjunction with CSPF and a dynamic
signaling protocol, such as RSVP-TE.

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 updates 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 changes to up.
To configure failed link timer:
Step
1. Enter system view.
2. Enter MPLS view.
3. Configure the CSPF failed link
timer.
