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.

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 C
ONFIGURE 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 A
SSIGN 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.
