Configuring the IAD as a bridge involves several tasks. These are all 
displayed and accessed on the Bridge Configuration menu (displayed by 
typing 3 on the Main menu). Each task in this chapter is described 
beginning at the Bridge Configuration menu.

You may sign on as Supervisor or Network Manager to configure the IAD 
as a bridge. Options that display in the Bridge Configuration menu are the 
same for both security levels. 

For bridging to function correctly, you must enable bridging both globally or 
by port and then set the bridge aging timer. At least two ports must be 
enabled for bridging to function. You must also disable RIP poisoned 
reverse. The order in which you perform the procedures is irrelevant.

To enable routing globally (Chapter 4, 

), 

you must disable bridging globally. However, you may enable routing on 
some ports and bridging on others, depending on your requirements. 

IP Over Bridging is intended for use then the IAD is in full bridged mode, 
but remote access (Telnet) and/or user authentication (RADIUS) are 
required.

Be sure to reset the IAD when you are done making changes 
to bridge configuration. Resetting the IAD causes the 
configuration changes to take effect.

 

When bridging is disabled globally or on an interface (port) or 
an IP address is unconfigured, IP Over Bridge is disabled 
automatically.
