Configuring Novell IPX

by creating a

virtual circuit

or connection between machines, with each

connection having a specific connection ID included in the SPX header.

RIP

Routing Information Protocol is a distance-vector routing protocol

used to discover IPX routes through internetworks. It employs ticks (1/18
of a second) and

hop counts

(number of routers between nodes) as metrics

for determining preferred routes.

SAP

Service Advertising Protocol is used to advertise and request ser-

vices. Servers use it to advertise the services they offer, and clients use it to
locate network services.

NLSP

NetWare Link Services Protocol is an advanced link-state routing

protocol developed by Novell. It's intended to replace both RIP and SAP.

Cisco EIGRP

Cisco Enhanced Interior Gateway Routing Protocol is a

proprietary routing protocol that can be used instead of IPX RIP. It is con-
sidered an advanced distance-vector routing protocol, but it uses some
link-state properties and some distance-vector properties to make routing
decisions and keep bandwidth usage at a minimum.

NCP

NetWare Core Protocol provides clients with access to server

resources; functions such as file access, printing, synchronization, and
security are all handled by NCP.

What does the presence of routing protocols, connection and connection-

less transport protocols, and application protocols indicate to you? All of
these factors add up to the fact that IPX is capable of supporting large inter-
networks running many applications. Understanding how Novell uses these
protocols clears the way for you to include third-party devices (such as Cisco
routers) into an IPX network.

Client-Server Communication

Novell NetWare follows a strict client-server model (there's no overlap): a
NetWare node is either a client or a server, and that is that. You won't find
peer machines that both provide and consume network resources here.
Clients can be workstations running MacOS, DOS, Microsoft Windows,
Windows NT, OS/2, Unix, or VMS. Servers generally run Novell NetWare.
NetWare servers provide the following services to clients:
