required between departments of Enterprise A, and between Enterprise A and remote Enterprises
C (in a different geographical location).
Departments of Enterprise A belong to the LANs on the same network segment, and therefore
they can be bridged to communicate with each other. Enterprise C, however, belongs to a LAN
on a different network segment. Therefore, link-layer bridging cannot meet the requirement of
the communication between Enterprise A and Enterprise C.
In this case, you can configure remote bridging integrated with IP routing to achieve the
communication between Enterprise A and Enterprise C.
