# Example: Configuring an IP Interface for a LAG Bundle

The following example displays configuration of LACP for two Fast Ethernet interfaces in slot 0. The interfaces are enabled for active LACP. The speed and duplex characteristics are the same for both interfaces.

host1(config)#interface fastEthernet 0/0 host1(config-if)#speed 100 host1(config-if)#duplex full host1(config-if)#lacp active host1(config-if)#interface fastEthernet 0/5 host1(config-if)#speed 100 host1(config-if)#duplex full host1(config-if)#lacp active

The following commands create a virtual router, add the Ethernet physical interfaces to a LAG bundle named bundleBoston, and assign an IP address and mask to the bundle.

host1(config)#virtual-router boston host1:boston(config)#interface lag boston host1:boston(config-if)#member-interface fastEthernet 0/0 host1:boston(config-if)#member-interface fastEthernet 0/5 host1:boston(config-if)#ip address 1.1.1.1 255.255.255.0
