OUTING
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.

or the Open Shortest Path First (OSPF) protocol. The Summit dynamically builds and

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.
