resilience sorted-pacing
Configures the router to establish LSPs one at a time using the defined timer and jitter, starting with the largest LSPs.
Syntax: [no] resilience sorted-pacing time {s | ms} jitter time
pacing time
Specifies the number of seconds or milliseconds the router waits before trying to establish an LSP. Valid values are 0.0 - 4294967.00 <s | ms> where s is seconds and ms is milliseconds.
jitter time
Specifies the number of seconds to offset to the pacing timer to prevent contention for resources when many LSPs are established.
Description: The resilience attribute determines how a tunnel responds when a network resource, that is in use by the tunnel, fails. There are four resilience methods: disabled, pacing, sorted-pacing and linear.
Sorted-pacing resilience means that the ingress router re-establishes LSPs one at a time, using the specified pacing interval and jitter. LSPs are re-established according to the bandwidth reserved for that LSP. Larger LSPs are established first. The sorted pacing model results in a more efficient packing of LSPs onto a link.
Use the resilience sorted pacing command to configure the ingress router to re-establish LSPs using the specified interval and jitter.
Use the no resilience sorted-pacing command delete a resilience specification.
Factory Default: Sorted pacing 5s jitter 1s.
Command Mode: Traffic engineering parameter-set, traffic engineering tunnel-default, and traffic engineering tunnel-name.
Example: In the following example, the resilience sorted-pacing command configures the tunnel to re-establish LSPs starting with the largest reservation amount and ending with the smallest reservation amount, using a 10 second delay between setups and with a jitter of 1 second:
router(config)#mpls te ospf
router(config-te)#tunnel oc12toBos
router(config-te-tunnel)#resilience sorted-pacing 10s jitter 1s
router(config-te-tunnel)#end
router#show mpls te tunnel
tunnel oc12toBos
