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 destinatio n 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.
PPP addresses 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.
PPP addresses 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.
