IP Network Interfaces
unnumbered interfaces (such as Example 2), then the connecting subnet would not be required.
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.

NTERFACES
Routing Information Protocol (RIP) is a protocol used to exchange routing information among IP
devices. Using IP RIP can automate the maintenance of routing tables on IP devices and relieve you
of having to keep the routing tables up to date manually. IP RIP determines the shortest path
between two points on a network in terms of the number of “hops” between those points.
LAN type interfaces (LAN and RLAN Interfaces) and WAN interfaces are used by devices to
advertise the IP RIP information. The type of interface used for IP RIP depends on the network
