host1(config-rsvp)#refresh-period 60000

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.
