Year 2 - Chapter 7/Cisco 3 -Module 7 Novell IPX Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com Objectives • • • • • • • Explain how Cisco routers are used in NetWare networks Describe the Novell NetWare protocol suite Describe Novell IPX addressing Describe Novell encapsulation Explain how Novell uses RIP for routing Describe Service Advertising Protocol Configure both the router Ethernet and serial interfaces with IPX addresses • Describe how to discover IPX addresses on remote routers • Describe how to verify IPX operation and connectivity between routers • Explain troubleshooting in IPX operations Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com The Novell NetWare Protocol Suite Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com Novell Protocols • Novell Netware is a proprietary suite of protocols and includes the following: – IPX, a connectionless Layer 3 protocol, that does not require an acknowledgment for each packet and defines the network and node addresses – Novell Routing Information Protocol (RIP), which is different from IP RIP, to facilitate the exchange of routing information – Service Advertising Protocol (SAP) to advertise network services – NetWare Core Protocol (NCP) to provide client-to-server connections and applications – Sequenced Packet Exchange (SPX) service for Layer 4 connection-oriented services Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com IPX Features Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com IPX Characteristics • It is used exclusively in a client/server environment. • It uses the network.node IPX addressing structure. • Its logical address contains an interface MAC address. • IPX interface configuration supports multiple datalink encapsulations (to support outdated IOS applications). • Novell RIP uses the distance-vector metrics of ticks and then hops. • Service Advertisement Protocol (SAP) and Get Nearest Server (GNS) broadcasts connect clients and servers. Copyright 2002 Cisco Press: CCNA Instructor’s Manual www.ciscopress.com IPX Addressing The recommended way to get a Novell network address is to ask the network administrator. If you cannot get the address from the network administrator, you can get the IPX address directly from a neighbor router. Telnet to the neighbor router and use the show protocols or show ipx interface command.
