Enable Policy Lookup
Perform these steps to enable policy lookup through AAA, beginning in global configuration mode:
Step 4
domain name
Example:
Router(config-isakmp-group)# domain
company.com
Router(config-isakmp-group)#
Specifies group domain membership.
Step 5
exit
Example:
Router(config-isakmp-group)# exit
Router(config)#
Exits IKE group policy configuration mode, and
enters global configuration mode.
Step 6
ip local pool {default | poolname}
[low-ip-address [high-ip-address]]
Example:
Router(config)# ip local pool dynpool
30.30.30.20 30.30.30.30
Router(config)#
Specifies a local address pool for the group.
For details about this command and additional

rtr-remote local
Router(config)#
Specifies AAA authentication of selected users at
