Cisco Cisco IOS Software Release 12.2(33)SRE

To configure the repair rate that Resource Reservation Protocol (RSVP) uses for a fast local repair (FLR) 
procedure, use the ip rsvp signalling fast-local-repair rate command in global configuration mode. To 
set the repair rate to its default, use the no form of this command.

ip rsvp signalling fast-local-repair rate rate 

If this command is not configured, the RSVP message pacing rate is used.

The RSVP message pacing rate is enabled by default in Cisco IOS Release 12.2 and later.

Global configuration

The default repair rate is based on the RSVP message pacing rate.

If you configure the FLR rate by using the ip rsvp signalling fast-local-repair rate command, and 
RSVP message pacing is enabled, the minimum between the FLR rate and the RSVP message pacing 
rate takes effect. If you disable the RSVP rate limit by using the no ip rsvp signalling rate-limit 
command, then the FLR rate is used. However, if you disable the RSVP rate limit and do not configure 
an FLR rate, then RSVP performs no message pacing and messages are sent back-to-back. This action 
is not recommended because the point of local repair (PLR) may flood the downstream node with PATH 
messages causing some of them to be dropped.

The repair rate is determined at notification time, and this same rate is used during the time of the repair 
even if you change either the RSVP message pacing rate or the FLR rate during this time.

The following example configures a repair rate of 100 messages per second:

Router(config)# ip rsvp signalling fast-local-repair rate 100

FLR rate for PATH state refresh and repair, in messages per second 
(msg/sec). The range is 0 to 5000. The default is 400.
