If your organization operates a TCP/IP network and needs to extend the
IP network over geographically remote sites, it is possible to bridge the
network using the Bridge/Router Module. It is only possible to bridge
where both sites have the same network address and the devices are
on the same subnet. In a class C IP address, the network address is the
first three groups of numbers. For example:
192.100.100.xxx
where xxx
represents the host ID of the individual devices on the subnet.
See
“IP Addresses”
in
AppendixA
for more information about addresses.
Typically IP bridging would be used to connect a back office or home office
into a main site. Any further network connections would be carried out
from the main site. An example of such a network is shown in
Figure 1-2
.
During configuration, you enter the ISDN number and the IP addresses
of any hosts to which you want to connect. In the example in
Figure 1-2
, the IP address of the host 191.100.100.100 is used. Only
when data destined for this device is received by the Bridge/Router
Module, is a call made to the remote site.
