200 Chapter 7: Configuring a Cisco 700 Series Router

The following guidelines should be known by the successful CCNP candidate:

Functions--LAN and internal profiles provide the same basic function.

LAN routing--Any protocol routed in the LAN must be routed in the user profile. If a
user profile does not declare routing, the LAN profile does not route it.

Bridging--Any protocol routed in the internal profile may be routed or bridged in the user
profile.

Pinging--If IP or IPX routing is on for the internal profile, the router can be pinged.

The system, LAN, and user profiles must be configured to establish a call. The system level is
similar to the IOS global configuration mode, and is where the switch type service profile
identifiers (SPIDs) (if needed) and local directory numbers are entered.

The IP address and mask for the Ethernet interface and the routing protocol are established in
the LAN profile. Again, this is similar to the configuration of interface E0 using the IOS
command set. The user profile declares the phone number, frame type, encapsulation, static
routing and authentication for this connection.

Once the profiles are created, they must be activated. An active profile is ready to accept a
demand call. To activate a profile once it is created, you would use

set active profile-name

where the profile-name is the freely chosen name of the connection. For example, suppose the
profile my_corp_off has been created and configured using the set user my_corp_off
command. The next step would be to activate the profile by issuing this command:

set active my_corp_off.

A more in-depth discussion of the syntax takes place later in the chapter.

Configuring the Cisco 700 Series Router for IP Routing

There are three sections to configuring a Cisco 700 series router--the system level, the LAN,
and the user profile.

The system profile contains that information that is generally found in the global configuration
on an IOS router. The information includes the name of the router and the switch type.
Additionally, the system level contains the encapsulation type, the authentication type, and the
password used by the 700 series router when it connects to another device. This information is
placed on the individual WAN interfaces on other router platforms; however, the fact that
encapsulation and the authentication type are NOT interface level parameters can be explained
by noting that that there is only one WAN interface on the 700.
