The three brouters are set up to tunnel one
or more protocols and each is a tunnel
partner to the other two brouters. This
configuration allows LAN A, LAN B, and
LAN C to become a virtual private Ethernet
network with the Internet as the transport
mechanism for data between them. The
encapsulated data packets can be optionally
encrypted to make the virtual private
network more secure.
