B.C.D
NOTE: Packets from the
internal network will be
routed to the next hop
at A.B.C.D. If interface
FastEthernet 0/0 goes
down, the route entry
will be purged from the
routing table and will
be reinstated only when
interface FastEthernet
0/0 goes back up. If only
an outbound interface
is speci?¬?ed in the
static route, the router
believes all destinations
to be directly connected
and will issue proxy
ARP requests.

Step 5: Apply NAT Programming
Con?¬?guring L2 Bridging Using a Cisco Cable Modem HWIC
The programming steps for setting up Layer 2 bridging using a Cisco cable modem High-
Speed WAN Interface Card (HWIC) are as follows:
Step 1. Configure global bridging parameters.
Step 2. Configure WAN to LAN bridging.
Step 1: Con?¬?gure Global Bridging Parameters
Edmonton(config)#interface fastethernet 0/1 Enters interface
con?¬?guration mode
Edmonton(config-if)#shutdown Turns off the interface
Edmonton(config-if)#ip nat inside De?¬?nes the interface as an
internal interface for the
NAT process
Edmonton(config-if)#no shutdown Enables the interface
Edmonton(config-if)#interface fastethernet 0/0 Enters interface
con?¬?guration mode
for FastEthernet 0/0
Edmonton(config-if)#shutdown Turns off the interface
Edmonton(config-if)#ip nat outside De?¬?nes the interface as the
external interface for the
NAT process
Edmonton(config-if)#no shutdown Enables the interface
Edmonton(config-if)#exit Exits interface
con?¬?guration mode
Edmonton(config)#exit Exits global con?¬?guration
mode
Router>enable Moves to privileged mode
Router#configure terminal Enters global
con?¬?guration mode
