Configure Graceful Restart: Examples

The example shows how to change the acknowledge hold time from the default value of 400 ms and how to
delay or speed up sending of ACKs. The maximum acknowledgment message default size is from 4096 bytes.
rsvp interface pos 0/4/0/1
signalling refresh reduction reliable ack-hold-time 1000
rsvp interface pos 0/4/0/1
signalling refresh reduction reliable ack-max-size 1000
Note Ensure retransmit time on the peers' interface is at least twice the amount of the ACK hold time to prevent
unnecessary retransmissions.

Summary Refresh Message Size Configuration: Example

The example shows how to set the summary refresh message maximum size to 1500 bytes.
rsvp interface pos 0/4/0/1
signalling refresh reduction summary max-size 1500

Disable Refresh Reduction: Example

If the peer node does not support refresh reduction, or for any other reason you want to disable refresh reduction
on an interface, the example shows how to disable refresh reduction on that interface.
rsvp interface pos 0/4/0/1
signalling refresh reduction disable
Configure Graceful Restart: Examples
RSVP graceful restart is configured globally or per interface (as are refresh-related parameters). These examples
show how to enable graceful restart, set the restart time, and change the hello message interval.

Enable Graceful Restart: Example

The example shows how to enable the RSVP graceful restart by default. If disabled, enable it with the following
command.
rsvp signalling graceful-restart
