Configuring Traffic Forwarding Tuning Parameters - 3Com S7906E Configuration Manual

To do...
Enable forwarding adjacency
If you use automatic route advertisement, it is required to specify the destination address of the TE
tunnel as the LSR ID of the peer.

Configuring Traffic Forwarding Tuning Parameters

In MPLS TE, you may configure traffic forwarding tuning parameters such as the failed link timer and
flooding thresholds to change paths that IP or MPLS traffic flows traverse or to define type of traffic that
may travel down a TE tunnel.
Configuration Prerequisites
The configurations described in this section are used in conjunction with CSPF and the dynamic
signaling protocol RSVP-TE.
Configuration Procedure
Configuring traffic forwarding tuning parameters involves these tasks:
Configuring the failed link timer
Configuring the link metric used for routing a tunnel
Configuring the traffic flow type of a tunnel
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...
Enter system view
Enter MPLS view
Configure the CSPF failed link
timer
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:
