Physical and Data-Link layers use existing standards
IPX - Internetwork Packet Exchange (Connectionless)
SPX - Sequence Packet Exchange - Transport Layer
SAP - Service Advertisement Protocol (Servers and Routers)
Addressing
IPX Network Address
- Unique across whole Netware environment (No subnets)
- 80 Bits - Hexadecimal - 20 digits
Network Number (32 bits - usually IPv4 network address) . Network ID (48 bits - usually MAC Address)

Routing
RIP, NLSP, or EIGRP
RIP
RIP enabled by default
Metric is TICK (Delay), hop count used as tie break
No compatible with IP RIP.
Max 16 hops.
