202 Chapter 7: Configuring a Cisco 700 Series Router
Example 7-1 shows the configuration file for the network setup in Figure 7-2.
The system commands establish the hostname of the 700, the switch type, the encapsulation,
and the authentication type and password. The password is the one used by the 700 when
connecting to the Corporate Office router. The authentication has been declared as PPP CHAP
both inbound and outbound. This is unique to the 700 IOS whereas in the non-700 IOS, the
declaration of authentication does not take on a direction.
The command cd lan changes the LAN profile. The commands in the LAN section assign the
IP address and mask and enable routing. You may be asking the following: "What routing
protocol is turned on?" The answer is RIP Version 1 (RIP-1). The router supports only RIP, and
by not specifying that RIP Version 2 (RIP-2) is to be used, the router uses RIP-1.
In the last section in Example 7-1, the user CorpOFF is created with the command set user
CorpOFF. The use of the command set user is used only to create the profile (subdirectory).
After the profile has been created, it can be accessed to alter the configuration by using the
command cd CorpOFF. This command works with any permanent profile.
The commands in the User section set an IP address for the WAN and turn on routing so that
the user profile during this call participates with the LAN profile. The phone number is set, and
