9IP Unicast Routing

This chapter describes how to configure IP routing on the Summit. It assumes that you are already familiar with IP unicast routing. If not, refer to the following publications for additional information:

RFC 1058

Routing Information Protocol

RFC 1256

ICMP Router Discovery Messages

RFC 1812

For more information on routing protocols, refer to Chapter 10.

OVERVIEW OF IP UNICAST ROUTING

The Summit provides full Layer 3, IP unicast routing. It exchanges routing information with other routers on the network using either the Routing Information Protocol (RIP) or the Open Shortest Path First (OSPF) protocol. The Summit dynamically builds and maintains a routing table, and determines the best path for each of its routes.

Each host using the IP unicast routing functionality of the Summit must have a unique IP address assigned. In addition, the default gateway assigned to the host must be the IP address of the Summit router interface.

RIP and OSPF are described in Chapter 10.
