Abstract

This document describes how Novell IPX operates over various WAN media. Specifically, it describes the common "IPX WAN" protocol Novell uses to exchange necessary router to router information prior to exchanging standard IPX routing information and traffic over WAN datalinks. This memo provides information for the Internet community. It does not specify an Internet standard.

1. Introduction

This document describes how Novell IPX operates over various WAN media. It is strongly motivated by a desire for IPX to treat ALL wide area links in the same manner. Sections 3 and 4 describe this common "IPX WAN" protocol.

RFC 1362 IPXWAN September 1992

IPX WAN protocol operation begins immediately after link establishment. While IPX is a connectionless datagram protocol, WANs are often connection-oriented. Different WANs have different methods of link establishment. The subsections of section 1 of this document describe what link establishment means to IPX for different media. They also describe other WAN-media-dependent aspects of IPX operation, such as protocol identification, frame encapsulation, and link tear down.

1.1 Operation Over PPP

IPX uses PPP [1] when operating over point-to-point synchronous and asynchronous networks.

With PPP, link establishment means the IPX NCP [4] reaches the Open state. NetWare IPX will reject all NCP options, and uses normal frame encapsulation as defined by PPP. The IPXWAN protocol MUST NOT occur until the IPX NCP reaches the Open state.

PPP allows either side of a connection to stop forwarding IPX if one end sends an IPXCP or an LCP Terminate-Request. When a router detects this, it will immediately reflect the...
