Terminology

Review the following IPX routing terms that are used extensively
throughout this chapter:
Address — Unique 4-byte network address of a segment that is
located in your Multilayer Switching Module's routing table.
Age — The time in seconds since the network's last update.
Cost — A number between 1 and 65534 that the system uses to
calculate route ticks. Assign a cost of 1 to each IPX interface unless
your network has special requirements like the need for redundant
paths.
Frame formats — Frame encapsulation format.
Hops — The number of routers that must be crossed to reach a
network segment.
Interface — The system-assigned number for an IPX interface.
NetBIOS protocol — Network Basic Input Output System protocol.
An application programming interface (API) that adds special
functions for PC-based LANs.
Node — The node address of the router that can forward packets to
each network segment (when this is set to all 0s, the router is directly
connected).
RIP — Routing Information Protocol. Allows the exchange of routing
information on a NetWare network. IPX routers use RIP to create and
maintain their dynamic routing tables.
SAP — Service Advertisement Protocol. Provides routers and servers
that contain SAP mode agents with a means of dynamically
exchanging network service information.
Ticks — An estimate of the time that is necessary to reach a network
segment. One second is 18.21 ticks.
VLAN interfaces — Your Multilayer Switching Module's point of
attachment to a given VLAN. A VLAN interface exists entirely within a
given IPX interface.
