116 CyberSWITCH
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.
