Figure 24. Local LAN Bridging and ATM Server Access
4.7.2.2 Campus LAN Interconnect and ATM Server Access
Figure 25 on page 61 shows an example of using the ATM-LAN bridge as a
means of bridging four LANs together with four LANs remotely, interconnecting
them with a high-speed ATM backbone while providing all users, including the
ATM25 users, with access to an ATM-attached server for very demanding
applications.
Note
All LANs configured on a specific module must be of the same type, Ethernet
or token-ring. Moreover, the workstations connected to that port will only be
able to communicate directly with other devices supporting that same kind of
LAN type, whether natively (via another ATM/LAN bridge), or via LAN
emulation. This limitation can be overcome using an ATM router such as the
IBM Multiprotocol Switched Services Server.
