Routing a Cisco 700 Series Router to an ISP Instructions

Following is the command summary for configuring the remote Cisco 700 series router to connect to an ISP:

set system 764 cd lan

set ip address 172.16.17.9

set ip netmask 255.255.255.248 set ip routing on

set user isp

set number 5558011

set ppp password client set ppp secret client

set ppp address negotiation local on set ip routing on

set ip route destination 0.0.0.0/0 gateway 0.0.0.0 propagate on set bridging off

set ip address 0.0.0.0 set ip netmask 0.0.0.0 set timeout 360

set ip pat on set active reboot

If you are being charged for each connection, you can use the set timeout command to set the timeout to zero. Doing so maintains your connection and minimizes the number of fees.

Routing IP to a Central Site

This section describes how to configure a remote Cisco 765 router and a central site Cisco 765 router for on-demand IP routing using PPP.

PPPaddresses issues that include the assignment and management of IP addresses,

asynchronous (start/stop) and bit-oriented synchronous encapsulation, network protocol multiplexing, error detection, and option negotiation.

PPPaddresses these issues by providing an extensible Link Control Protocol (LCP) and a family of Network Control Protocols (NCPs) to negotiate optional configuration parameters and facilities. PPP supports IP and IPX.

Figure 3-3 is an illustration of the configuration used in this example.
