Example 2: LAN, WAN UnNumbered, WAN Remote LAN Interfaces

In example 2, the WAN UnNumbered interface is used to eliminate an unnecessary IP Subnet. The RLAN interface is unique in that it extends the IP network over the WAN to remote devices which access the network using a bridge device. Thus it makes a simple bridge device appear to be an IP router. This is accomplished by having the system extend its Ethernet to handle the ARPs for the remote bridge.
