host1(config-rsvp)# refresh-period 60000
host1(config-rsvp)# cleanup-timeout-factor 9
3.
(Optional) Configure retry timer options globally (to apply to all tunnels) to set up
an LSP after a setup failure (a failure
other than one due to no available route).
Specify the number of attempts to be made to set up an RSVP-TE tunnel or the
interval in seconds between attempts.
host1(config)# mpls lsp retries 35
host1(config)# mpls lsp retry-time 55
4.
(Optional) Configure retry timer options globally (to apply to all tunnels) to set up
an LSP after a failure due to no available route. Specify the number of attempts to
be made to set up an RSVP-TE tunnel or the interval in seconds between attempts.
host1(config)# mpls lsp no-route retries 3200
host1(config)# mpls lsp no-route retry-time 45
5.
(Optional) Configure the interval at which the bandwidth values are flooded.
host1(config)# mpls traffic-eng link-management timers periodic-flooding 10
6.
(Optional) Configure reoptimization—the frequency at which MPLS searches for
better paths for existing tunnels.
NOTE: Low timer values lead to frequent reoptimization of LSPs, which is undesirable
for the following reasons:
•
Frequent changes to the LSPs increases packet loss.
•
Frequent reoptimization increases the load on the router, especially when the router
acts as the LSP head end. The load is particularly noticeable in a scaled network,
resulting in high CPU utilization on the router.
host1(config)# mpls reoptimize timers frequency 180
You can also force an immediate search for better paths for all existing LSPs.
host1# mpls reoptimize
7.
(Optional) Enable refresh reduction and message bundling.
host1(config)# mpls rsvp refresh-reduction
host1(config)# mpls rsvp message-bundling
8.
(Optional) Configure the egress router to advertise the explicit null label.
host1(config)# mpls rsvp egress-label explicit-null
LDP and RSVP-TE Interface Profile Configuration Tasks
The interface profile configuration tasks are optional tasks you may need to perform to
configure your network’s label distribution options.
