Technical Summary:
ESADI (End Station Address Distribution Information) is an optional
protocol implemented at TRILL switches by which they can
communicate, in a Data Label (VLAN or Fine Grained Label) scoped
way, end station addresses and other information to TRILL switches
in the TRILL campus participating in ESADI for that Data Label.
This document updates the specification of the ESADI protocol that
appears in RFC 6325, the TRILL base protocol specification, and is
not backwards compatible because it changes the format of
ESADI-LSPs.
Working Group Summary:
There was no particular controversy. Before the initial WG Last Call
on the -02 draft there was a late IPR disclosure filed. There were
WG Last Call comments leading to editorial and technical changes
resulting in the 03 draft which was determine to have WG consensus.
The -03 draft increased the number of fragments in an ESADI-LSP and, as a
result of document Shepherd review, the WG was asked if it wanted
to change to the standard method for doing this which was
progressing as draft-ietf-isis-fs-lsp. Based on WG support for this
change, a -04 draft was produced and a 2nd WG LC starting on 27
November 2013. During this WG LC a specific technical problem with
a corner case was uncovered and it was suggested that an expanded
explanation of how this document will update the TRILL base
specification [RFC6325] should be included. A fix to this technical
problem and the expanded "updates" explanation were included in in
the -05 draft which was WG Last Called on 8 Feb 2014 and determined
to have consensus.
Document Quality:
The shepherd doesn't know of existing implementations. There has been
significant review of this document on the TRILL WG mailing list with
multiple WG last calls.

Although this document creates an additional IANA sub-registry,
it does not require expert review, hence no experts are proposed.
