Connection Processes of the LEC-to-LE Service

Address Registration

The address registration function is the mechanism by which LECs provide
address information to the LAN Emulation Server. The LAN destinations
may also be unregistered as the state of the client changes. A Client must
either register all LAN destinations for which it is responsible, or join as a
proxy to other MAC addresses.
