Configuring IPX Routing Protocols

In Chapter 4, we discussed the following issues, which you need to consider when choosing a dynamic routing protocol:

• Network topology

• Address and route summarization

• Convergence speed

• Route selection criteria

• Scalability

• Ease of implementation

• Security

In the Cisco IOS, there are multiple dynamic IPX routing protocols. When choosing the optimal protocol for your network, you need to consider the preceding criteria.

Before delving into the individual dynamic routing protocols, however, we must consider SAP. SAP is a dynamic service protocol that is tightly coupled with dynamic IPX routing protocols. After explaining SAP, we discuss the IPX dynamic routing protocols IPX RIP, NLSP, and IPX EIGRP.
