Permanent Profiles
Cisco 700 series routers contain three permanent profiles. Permanent profiles can be modified, but they cannot be deleted. The permanent profiles are as follows:
LAN | Determines how data is passed from the router to the LAN. This profile |
| is commonly used for connections made directly to the local network. |
Internal | Determines how data is passed between the bridge engine and the IP/IPX |
| router. |
Standard | The default profile. If authentication is set to none and a profile does not |
| exist for the WAN switch, the router uses the Standard profile by default. |
| If authentication is required and no profile is found, the call is dropped. |
The decision to use the LAN or Internal profile involves some knowledge of your network design and whether you are bridging or routing to remote sites (or a combination of both). It is best to use the LAN profile instead of the Internal profile to simplify the configuration.
You can easily associate the LAN profile with the Ethernet interface and the
Sometimes situations arise (very infrequent) where you must route a protocol to one site and bridge the same protocol to another site. Simply leave the LAN profile as a bridging profile, and use the Internal profile for all routed protocol information.
