Bridge Mode Compatibility
Most members of the MBE range of products are intercompatible (see
Table 1-1 ) .
Additional bridges cannot be connected to the remote LAN. However, no
limitations on additional bridging or routing apply to the main LAN.

Principles of Operation
MBE10-1 Operation
The remote MBE learns the address of the remote workstation connected to it
when the workstation attempts to access the network. The remote MBE then uses
this workstation address to request the local MBE to insert into the local (main)
LAN. The remote MBE forwards all frames originating from the remote
workstation. The local MBE will forward to the link only those frames destined for
the remote workstation including broadcast and multicast messages, unless they
have been masked out.
MBE10-1D Operation
The remote MBE units on both links update the local MBE with the addresses of
the remote workstation attached to it. Each remote MBE forwards to the link all
frames destined for the local LAN. The local MBE forwards to a particular link only
those frames destined for a workstation connected to that link. Broadcast and
multicast messages are forwarded to both links, unless they have been masked out.
