3.1 IPX Protocol Overview
The internetwork packet exchange (IPX) protocol is a network layer protocol in the
NetWare protocol suite. IPX's position in the Novell Netware protocol is similar to that of
IP in the TCP/IP protocol suite. IPX can address, route and forward packets.
IPX is a connectionless protocol. Though an IPX packet contains a destination IPX
address in addition to the data, IPX does not ensure that packets are forwarded to the
destination successfully. Packet forwarding results and connection control must be
provided by protocols above IPX. In IPX, each IPX packet is considered as an
independent entity that has no logical or sequential relationship with any other IPX
packets.
IPX Address Structure
IPX and IP use different address structure. An IPX address comprises two parts: the
network number and the node address; it is in the format of "network.node".
A network number identifies the network where a site is located. It is four bytes long and
expressed by eight hexadecimal numbers. A node address identifies a node on the
network. Like an MAC address, it is six bytes long and comprises three 2-byte numbers
(separated from each other using "-"). The node address cannot be a broadcast or
multicast address. For example, in the IPX address bc.0-0cb-47, bc (or 000000bc) is
the network number and 0-0cb-47 (0000-00cb-0047) is the node address. You can also
write an IPX address in the form of N.H-H-H, where N is the network number and H-H-H
is the node address.

3.1.1 Routing Information Protocol

IPX uses the routing information protocol (RIP) to maintain and advertise dynamic
routing information. With IPX enabled, the switch exchanges routing information with
other neighbors through RIP to maintain an inter-network routing information database
(also known as a routing table) to accommodate to network changes. When the switch
receives a packet, it looks up the routing table for the next site and forwards a packet (if
available). The routing information can be configured statically or collected dynamically.
