How to Implement General IPSec Configurations for IPSec Networks
Purpose
(Optional) Manually specifies the IP Security session key to
set the outbound IPSec session key for ESP.
The length of the keys should match the encryption or
authentication method that is specified in the transform-set.
Use the spi argument to specify the SPI, a number that
•
is used to uniquely identify a security association. The
SPI is an arbitrary number you assign in the range of
256 to 4,294,967,295 (FFFF FFFF).
Use the cipher keyword to specify the key string to be
•
used with the ESP encryption transform.
Use the hex-key-data argument to specify the session
•
key; enter in hexadecimal format. This is an arbitrary
hexadecimal string of 8, 16, or 20 bytes.
Use the authentication keyword to specify that the key
•
string is used with the ESP authentication transform.
The authentication keyword is required only when the
transform set includes an ESP authentication
transform.
Exits profile configuration mode.
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.
