Technical Summary
The IETF has standardized the TRILL protocol, which provides
transparent Layer 2 forwarding using encapsulation with a hop count
and IS-IS link state routing. This document specifies the data
formats and code points for the IS-IS extensions to support TRILL.
Working Group Summary
This document, draft-ietf-isis-ieee-aq and draft-ietf-isis-layer2 were
originally one document.Through the review process it was
determined that a split into a base document (draft-ietf-isis-layer2)
and draft-ietf-isis-trill and draft-ietf-isis-ieee-aq into separate
documents. One solution to pass layer2 information in ISIS or at
least one specification was desired but, the IEEE and IETF have each
defined their own mechanism. Given the divergence of solutions, a
specification split was appropriate.
Document Quality
There are known interoperable implementations of this technology
based in earlier versions of the drafts. Earlier versions were based
on additional PDUs in the ISIS protocol which have been changed
to TLVs. It is reasonable that implementors can make the change
and that earlier interoperation demonstrates that the solution
is viable.
