ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

Create this dialer script in an ASCII file and copy it to the Router boot diskette. Use the dialup script command to configure your Router to use this dialing script.

#CISCO.DCF send “AT\r” wait 1000 “OK” send $PHONE connect

send “\r\r” 100

wait l0000 “Username:” send $LOGIN_NAME wait 1000 “Password:” send $LOGIN_PWD

send “ppp\r”

wait 2000 “MTU is 1500 bytes” status up

D.4 IPX Synchronous Routers

This information only applies to the Sync Router.

When connecting a Router to multiprotocol routers from other vendors, we recommend running the synchronous links in standard PPP mode (called IPXCP).

D.5 TCP/lP Synchronous Routers

D.5.1 CONFIGURE ROUTER TO USE PPP

Although each type of router may have a preferred, proprietary link encapsulation method, they all allow PPP as an alternative, so consider using PPP. Refer to your router’s documentation to find the exact command to select PPP encapsulation.

D.5.2 CONFIGURE ROUTER TO USE RIP

Each type of router also has a preferred internal routing protocol, such as IGRP or OSPF, but they all allow using RIP as an alternative on a specific network. Again, refer to your vendor’s documentation to find the exact command to configure the router for RIP.

D.5.3 ASSIGN SUBNET TO PPP CONNECTION IF NECESSARY

The Router doesn’t require you to assign a subnet number to the PPP connection between two routers (via modem or leased line), although some routers do. If you want to connect to a router that requires you to assign a subnet number to the PPP connection, then on the Router:

1.Assign a subnet number for the link between the two routers. On the Router, use the ifconfig sync0 address/bits up command.

2.Configure the Router to use the other router’s address (on that link) as the remote IP address.

3.Complete the Router configuration process.

4.Save the Router’s configuration.

Some routers (such as Wellfleet®) may require you to explicitly insert the remote node’s IP address in an “adjacent host” table.
