OUTING
The Summit provides full Layer 3, IP unicast routing. It exchanges routing information
with other routers on the network using the Routing Information Protocol (RIP). 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.

NTERFACES
The routing software and hardware routes IP trafÞc between router interfaces. A router
interface is simply a VLAN that has an IP address assigned to it.
