Configuring the Cisco 700 Series Router for IP Routing 203

the default gateway is established. In effect, the static route says if the packet isn't for me, send
it to 10.33.33.2, which is the other side of the WAN link. It is important to note that a static route
is required on the CorpOFF router to gain access to the Ethernet or LAN of the 700 series router
because RIP updates have not been turned on.

To turn on RIP updates, you would need the command set RIP update periodic; however,
using a distance vector protocol over a dial-on-demand link to maintain route table entries
would not be cost effective.

The successful CCNP candidate should understand the profile location of the commands, the
interoperability with the IOS command set, and the features available on the router.

Profile Configuration Commands for the Cisco 700 Series Routers

Profile commands are used to establish the basics of the 700 series router configuration. The
commands can be categorized for use in the three basic profiles used. Table 7-2 summarizes the
commands used for the three basic profiles.

Command

Description

System

set switch

This command declares the switch type for the 700
series router. Valid choices would be DMS100,
5ESS, NI1, and so on. Because the 700 series router
only supports a single BRI interface, there is no need
for further definition of the switch type.

set encapsulation

This command declares the encapsulation method for
the BRI connection. The choices here are PPP and
CPPP. PPP would be the most common setting.

set ppp authentication
incoming

This command declares the authentication type for
an incoming call. The choices are CHAP, PAP, or
NONE. This feature is unique to the 700 IOS and
enables the authentication to take on a direction.

set ppp authentication
outgoing

This command is similar to the incoming authentication,
but declares the method of authentication for calls
leaving the 700 series router. Again, the method
choices are CHAP, PAP, and NONE.

set ppp secret

This command declares the password for the
700 series router that is used for all calls leaving the
700. This password would be used by PAP or CHAP as
declared by the set ppp authentication outgoing
command.
