Overview of IP Unicast Routing

The switch 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 switch 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 switch must have a unique IP address

assigned. In addition, the default gateway assigned to the host must be the IP address of the router

interface.
