| In order to forward a data packet, a
sending device must first know what routers are connected to the
local network and which Route Processor maintains the shortest path
to the destination device. Because it is not the responsibility of
the end-user device to create and maintain routing tables, a default
gateway is used to forward all nonlocal packets.
To define a gateway on a Cisco IOS Software-based series switch, enter the following command in global configuration mode.
Where ip-address is the IP address of the default Route Processor. A switch acts like any other IP end station and must have a default gateway configured in order for the switch to communicate with devices in other IP subnets. To do this, a default route must be added that points to the gateway router in the same subnet/VLAN as the sc0 interface on the switch. The sc0 interface is a virtual management interface on the Catalyst 4000 switch. To configure a default route on a set command-based system, enter the following command in privileged mode:
