Title : RBridges: The ESADI Protocol

Pages : 22

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 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.
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 can receive remote address
information and/or transmit local address information for VLAN-x to
other such RBridges. The purpose of this document is to improve and
update the documentation of the ESADI protocol. It updates RFC 6325.
The ESADI RBridge instance states, DRB (Designated RBridge) election
procedure, and ESADI sub-TLV are specified in this document.
