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

This sample configuration dynamically routes IPX between a 700 series router and a Cisco IOS router using snapshot IPX RIP/SAP and PPP with CHAP authentication over ISDN. With snapshot RIP/SAP, IPX route and service updates are exchanged between routers during a user configured interval rather than the constant periodic exchange required of normal IPX RIP/SAP. Aside from this snapshot interval, the ISDN line activates only when traffic demands. This is known as dial-on-demand routing (DDR). In contrast, the periodic exchange of normal RIP would force the ISDN line to be permanently active, potentially resulting in high ISDN costs.

An alternative to DDR using a snapshot routing protocol is DDR using static routes. Routing tables are statically created by the network administrator eliminating the need for snapshot routing exchanges. For smaller networks, static routes may suffice. However, for larger networks, manually maintaining static routing tables on every router can be an administrative chore. Fortunately, the duration and frequency of the snapshot routing interval can be configured such that any ISDN costs due to dynamic routing are relatively negligible compared with the benefits of simplified network administration.
