Chapter 1: Understanding ISDN and the Express XL/XLT

IPX Routing

Like IP routing, the Express XL/XLT can connect to two different sites and ex- change IPX packets. Network routes and services are learned and advertised using Novell’s RIP and SAP. Routes and services learned from a separate site can be retained in the Express XL/XLT when the connection goes idle. While retained, the Express XL/XLT can spoof RIP/SAP and watch-dog and filter se- rialization packets that would normally be required between the Novell server and client.

Connection List - Simplifying and Enhancing the Dial Function

The Connection List, which is accessed from the Configuration menu, pro- vides a location to define information regarding 15 individual destinations that may be dialed. A Connection List entry is required for each destination since authentication information (method, username, password), number of B-channels, telephone numbers, Caller ID, IP, or IPX address (for routed con- nections), and other information can be stored for each destination defined. Defined destinations may be dialed by selecting the Dial activator in the Dial menu or by demand for the desired Connection List profile.

Concurrent Routing And Bridging

The Express XL/XLT can route IP and IPX as well as bridge non-IP/IPX pack- ets simultaneously. The Connection List profile will by default negotiate PPP network protocols to support the transmission and reception of IP, IPX, and Bridge packets. If the PPP peer does not accept a protocol, the Express XL/XLT will fall back to any combination of routing and bridging.

Routing over PPP Bridging

The Express XL/XLT can support legacy equipment which does not support

PPPIP (IPCP) or IPX (IPXCP) protocols by allowing routing packets over the WAN connection using PPP Bridging (BCP). To perform this, the Express XL/ XLT uses a “virtual” ethernet port. This port is set up under the Configura- tion/Bridge menu.
