TRILL (Transparent Interconnection of Lots of Links):
ESADI (End Station Address Distribution Information) Protocol
<draft-ietf-trill-esadi-02.txt>
Abstract
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
link technologies. TRILL supports multi-pathing of both unicast and
multicast traffic. Devices that implement the TRILL protocol are
called RBridges (Routing Bridges) or TRILL Switches.
ESADI (End Station Address Distribution Information) is an optional
protocol by which a TRILL switch can communicate, in a Data Label
(VLAN or Fine Grained Label) scoped way, end station addresses and
other information to TRILL switches pariticipating in ESADI for the
relevant Data Label. This document updates RFC 6325, specifically
the documentation of the ESADI protocol.
Status of This Memo
This Internet-Draft is submitted to IETF in full conformance with the
provisions of BCP 78 and BCP 79.
Distribution of this document is unlimited. Comments should be sent
to the TRILL working group mailing list: <rbridge@postel.org>.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
other groups may also distribute working documents as Internet-
Drafts.
