Leased Line: Static IP And IPX Routing

Leased Line Sample Configuration Static IP And IPX Routing	Cisco ConfigMaker Windows 95/NT 4.0 configuration tool

This sample configuration routes both TCP/IP and IPX between two Cisco routers over a synchronous serial line. Static IP routes and static IPX routes and services must be manually created on every router for each desired destination. For smaller networks, static routing may suffice. However, for larger networks, manually maintaining static routing tables on every router can be an undesirable administrative chore.

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. Separate IP network subnets are required at each site.
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.
