IP ROUTING

Web - Click IP, General, Routing Interface. Specify an IP interface for each VLAN that will support routing to other subnets. First specify a primary address, and click Set IP Configuration. If you need to assign secondary addresses, enter these addresses one at a time, and click Set IP Configuration after entering each address.

CLI - This example sets a primary IP address for VLAN 1, and then adds a secondary IP address for a different subnet also attached to this router interface.

Console(config)#interface vlan 1
Console(config-if)#ip address 10.1.0.253 255.255.255.0	4-216

Console(config-if)#ip address 10.1.9.253 255.255.255.0 secondary Console(config-if)#

Address Resolution Protocol

If IP routing is enabled (page 3-154),the router uses its routing tables to make routing decisions, and uses Address Resolution Protocol (ARP) to forward traffic from one hop to the next. ARP is used to map an IP address to a physical layer (i.e., MAC) address. When an IP frame is received by this router (or any standards- based router), it first looks up the MAC address corresponding to the destination IP address in the ARP cache. If the address is found, the router writes the MAC address into the
