Procedure Configuring IP Unicast Routing Enabling Directed Broadcast-to-Physical Broadcast Translation Command or Action Purpose Step 1 enable Example: Device>enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device#configure terminal Enters global configuration mode. Step 3 interface interface-id Example: Device(config)#interface gigabitethernet 1/0/2 Enters interface configuration mode, and specifies the interface to configure. Step 4 ip network-broadcast Example: Device(config-if)#ip network-broadcast Enables the ingress interface to receive and accept the network-prefix-directed broadcast packets. Step 5 exit Example:
Device(config-if)#exit Returns to global configuration mode. Step 6 interface interface-id Example: Device(config)#interface gigabitethernet 1/0/3 Enters interface configuration mode, and specifies the interface to configure. Step 7 ip directed-broadcast [access-list-number] Example: Device(config-if)#ip directed-broadcast 103 Enables directed broadcast-to-physical broadcast translation on the interface. You can include an access list to control which broadcasts are forwarded. When an access list, only IP packets permitted by the access list can be translated. Step 8 exit Example: Device(config-if)#exit Returns to global configuration mode. Configuring IP Unicast Routing 23
