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. 

 

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.  

The configurations described in this section are used in conjunction with CSPF and the dynamic 
signaling protocol RSVP-TE. 

Configuring traffic forwarding tuning parameters involves these tasks:

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:

The default is 10 seconds.  

 

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:
