Title : RBridges: The ESADI Protocol

The IETF TRILL (TRansparent Interconnection of Lots of Links)
protocol provides least cost pair-wise data forwarding without
configuration in multi-hop networks with arbitrary topologies and
safe forwarding even during periods of temporary loops. TRILL
supports VLANs and the multi-pathing of both unicast and multicast
traffic. TRILL accomplishes this by using IS-IS (Intermediate System
to Intermediate System) link state routing and encapsulating traffic
using a header that includes a hop count. Devices that implement
TRILL are called RBridges (Routing Bridges).
The ESADI (End System Address Distribution Information) protocol is a
VLAN (Virtual Local Area Network) scoped way that RBridge can
communicate end station addresses to each other. An RBridge
announcing VLAN-x connectivity (normally a VLAN-x forwarder) and
running the TRILL ESADI protocol receives remote address information
and/or transmits local address information for VLAN-x. The purpose
of this document is to improve the documentation of the ESADI
protocol. The ESADI RBridge instance states, DRB (Designated
RBridge) election procedure, and ESADI sub-TLVs are specified in this
document.
