Implementing IPSec Network Security on Cisco IOS XR Software
Purpose
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.
(Optional) Clears existing security associations, which
causes any existing SAs to expire immediately.
Future SAs use the new lifetimes.
•
Any existing SAs expire according to the previously
•
configured lifetimes.
Using the clear crypto ipsec sa command with the
Note
all keyword clears the full SA database, which
clears active security sessions. You may also
specify the sa-id argument to clear an SA with a
specific ID. For more information, see the clear
crypto ipsec sa command.
