Just as the diagram shows there are two interfaces on different VLANs that need to be merged as one. Here is the simple config to make this happen:

Router(config)#bridge irb
Router(config)#interface fa0/0
Router(config-if)#bridge-group 1
Router(config)#interface fa0/1
Router(config-if)#bridge-group 1

Router(config)#interface BVI1
Router(config-if)#ip address

Router(config)#bridge 1 protocol ieee
Router(config)#bridge 1 route ip
