Cisco IOS XR Routing Configuration Guide
Step 4
nsf interface-expires
number
Example:
RP/0/RP0/CPU0:router(config-isis)# nsf
interface-expires 1
Configures the number of resends of an acknowledged
NSF-restart acknowledgment.
• If the resend limit is reached during the NSF restart, the
restart falls back to a cold restart.
Step 5
nsf interface-timer
seconds
Example:
RP/0/RP0/CPU0:router(config-isis) nsf
interface-timer 15
Configures the number of seconds to wait for each restart
acknowledgment.
Step 6
nsf lifetime
seconds
Example:
RP/0/RP0/CPU0:router(config-isis)# nsf lifetime
20
Configures the maximum route lifetime following an NSF
restart.
• This command should be configured to the length of
time required to perform a full NSF restart because it is
the amount of time that the Routing Information Base
(RIB) retains the routes during the restart.
• Setting this value too high results in stale routes.
• Setting this value too low could result in routes purged
too soon.
Step 7
end
or
commit
Example:
RP/0/RP0/CPU0:router(config-isis)# end
or
RP/0/RP0/CPU0:router(config-isis)# commit
Saves configuration changes.
• When you issue the end command, the system prompts
you to commit changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
–
Entering yes saves configuration changes to the
running configuration file, exits the configuration
session, and returns the router to EXEC mode.
–
Entering no exits the configuration session and
returns the router to EXEC mode without
committing the configuration changes.
–
Entering cancel leaves the router in the current
configuration session without exiting or
committing the configuration changes.
• Use the commit command to save the configuration
changes to the running configuration file and remain
within the configuration session.
Step 8
show running-config [
command
]
Example:
RP/0/RP0/CPU0:router# show running-config
router isis isp
(Optional) Displays the entire contents of the currently
running configuration file or a subset of that file.
• Verify that “nsf” appears in the IS-IS configuration of
the NSF-aware device.
• This example shows the contents of the configuration
file for the “isp” instance only.
