Bridging 1-9
Local And Remote Bridges
There are two main types of bridge, local and remote. The
LinkBuilder MSH 4 Port Ethernet Bridge Module is a local bridge.
Local bridges are used for bridging networks on the same site, as
shown in Figure 1-6.
Figure 1-6 Local Bridge
Remote bridges are used for bridging netwo rks across large areas.
A remote bridge is often called a half bridge because each
network connects to half of the remote bridge. The remote
bridge halves are connected by a Wide Area Network (WAN) link,
as shown in Figure 1-7.

Both types of bridge have essentially the same op eration and
functionality.
