C ONFIGURING IP N ETWORK I NFORMATION
IP Network Concepts
In Example 2, the WAN UnNumbered interface is used to eliminate an unnecessary IP Subnet. The
Remote LAN interface is unique in that it extends the IP network over the WAN to remote users
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.
STATIC ROUTES
You only need to configure static routing entries if you need to access a WAN network that is not
directly connected to the system, or if you need to access a LAN network through a router that does
not support IP RIP. Static routes specify the IP address of the next hop router or gateway that
provides access to this subnet.
