Leased Line: Dynamic IPX Routing; Bridging All Other Protocols

Leased Line Sample Configuration Routing IPX; Bridging All Other Protocols	Cisco ConfigMaker Windows 95/NT 4.0 configuration tool

Note: The following configuration is for IPX only. It is a good idea to consider adding TCP/IP to the routers as well as IPX. Even though your network demands are strictly IPX, having TCP/IP on the routers will allow easier management and configuration through a remote telnet session.

This sample configuration routes IPX and bridges all other protocols between two Cisco routers over a synchronous serial line. IPX RIP/SAP dynamically resolves IPX routes and services. The IP addresses included in the example is strictly for remote management via telnet. Notice that both routers are on the same IP network number since IP is bridged.

The default encapsulation type used on leased lines between two Cisco routers is HDLC. However, when connecting to a non-Cisco router, PPP encapsulation must be used for third party compatability. This example also discusses how PPP encapsulation can be easily substituted in place of HDLC.

Preconfiguration Checklist

Leased Line Information
The following info must be gathered from the circuit provider

DSU/CSU Information
The circuit provider must provide clocking, data framing, and line encoding information to configure DSU/CSU successfully.

Network Information
The following info must be gathered from the network administrator

IP Address Information
An IP network design must be created if router management via telnet is desired
IPX Address Information
An IPX network design must be created. Each network segment requires a unique IPX network number.

Note: Commands followed by a <*> are on by default and do not have to be configured. The "!" marks that appear in the configuration are automatically entered by the router and function as line separators for easier reading.
