Upgrading Router Software with Unified ISSU
Protocol Timers
RIP Use the default timers; graceful restart is not supported. For scaled
configurations, such as for 2000 RIP interfaces, use the following
values:
Flush interval: 600 seconds
Holddown time: 260 seconds
Invalid interval: 260 seconds
Update interval: 60 seconds
RSVP-TE Use the default timers, including graceful restart default timers, except
for the following:
For graceful restart, the hello timeout interval is the product of
hello misses multiplied by the hello refresh interval. Determine
which period is longer, the IC upgrade time or the forwarding
upgrade time. Configure the hello refresh and hello miss values
so that the hello timeout is greater than the longer of those two
periods.
For node hellos, the product of the refresh misses multiplied by
the hello refresh interval must be great than the FC outage time.
For an outage time of less than 30 seconds, for example,
configure the following values:
Application Support for Unified ISSU on page 71
Disable autosynchronization.
host1(config)#disable-autosync
Copy the new release to the router.
host1#copy /incoming/releases/ftpserver/quebec2.rel R2.rel
Save the current configuration.
host1#copy running-configuration system2.cnf
Set the node hello refresh interval to 8000.
Set the node hello refresh misses to 4.
