Cisco Cisco IOS Software Release 12.2(33)SRE

To configure the number of per flow notifications that Resource Reservation Protocol (RSVP) processes 
during a fast local repair (FLR) procedure before suspending, use the ip rsvp signalling 
fast-local-repair notifications command in global configuration mode. To set the number of 
notifications to its default, use the no form of this command.

ip rsvp signalling fast-local-repair notifications number 

There are always notifications sent by the routing information base (RIB) and processed by RSVP. If this 
command is not configured, RSVP processes 1000 notifications, suspends, then resumes processing of 
another 1000 notifications, and so on.

Global configuration

Upon a route change, RIB builds a list of notifications, one per affected flow, and notifies RSVP by 
sending an event including these notifications. Therefore, these events can contain thousands of elements 
depending on the number of path state blocks (PSBs) affected. 

RSVP processes, by default, 1000 notifications at a time and then suspends if required, to prevent the 
CPU from being overwhelmed. However, you can configure this number using the ip rsvp signalling 
fast-local-repair notifications command.

The following example configures the number of flows that are repaired before RSVP suspends to 100:

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

Total number of notifications to be sent. The range is 10 to 10000. The 
default is 1000.

12.2(33)SRB

This command was introduced.

Configures the repair rate that RSVP uses for an FLR procedure.
