Configuration/Bridge
The Bridge menu is used to set up the bridge parameters for the
Router Option Module. The bridging function runs at the Media Ac-
cess Control (MAC) level which allows any protocol packets that
run over Ethernet to be forwarded. Bridging can run concurrently
with the IP and IPX routing. However, when packets are bridged
across a WAN connection, the following rules apply:
• When IP routing is active, IP packets (which include ARP pack-
ets) are not bridged.
• When IPX routing is active, IPX packets are not bridged.
• The WAN IP Bridge and WAN IPX Bridge menus allow the
WAN connection to bridge packets to the Router Option Module
but get routed as soon as they arrive at the unit.
Figure 4-5 shows the Bridge menu.

bridge functionality.
