Configure Group Policy Information
To configure the group policy, follow these steps, beginning in global configuration mode.
SUMMARY STEPS
1. crypto isakmp client configuration group {group-name | default}
2. key name
3. dns primary-server
4. domain name
5. exit
6. ip local pool {default | poolname} [low-ip-address [high-ip-address]]
DETAILED STEPS
Step 6
lifetime seconds
Example:
Router(config-isakmp)# lifetime 480
Router(config-isakmp)#
Specifies the lifetime, from 60 to 86400 seconds,
for an IKE SA
5
.
Step 7
exit
Example:
Router(config-isakmp)# exit
Router(config)#
Exits IKE policy configuration mode and enters
global configuration mode.
1. ISAKMP = Internet Security Association Key and Management Protocol
2. DES = data encryption standard
3. MD5 = Message Digest 5
4. SHA-1 = Secure Hash standard
5. SA = security association

Step 1
crypto isakmp client configuration group
{group-name | default}
Example:
Router(config)# crypto isakmp client
configuration group rtr-remote
Router(config-isakmp-group)#

to be downloaded to the remote client.
Also enters the ISAKMP group policy
configuration mode.
Step 2

Example:
Router(config-isakmp-group)# key
secret-password
Router(config-isakmp-group)#
Specifies the IKE pre-shared key for the group
policy.
