Technical Summary
Active-active access at the TRILL edge is the extension of flow
level multi-pathing and rapid fail-over service available in the
interior of a TRILL campus to end stations that are multiply
connected to a TRILL campus edge as discussed in RFC 7379. In this
document, a Virtual RBridge's pseudo-nickname represents the edge
RBridge group providing active-active access to such an end
station.
Working Group Summary
Early discussion in the TRILL WG favored a pseudo-node nickname
approach similar to that in this draft. Later analysis resulted in
the three alternatives described in the Introduction to
draft-ietf-trill-aa-multi-attach. Two of these, which can be
deployed simultaneously in a TRILL campus, are being advanced by
the WG, an evolved version of alternative 1 using a pseudo-nickname
in this draft and alternative 3 in draft-ietf-trill-aa-multi-
attach.
There was good WG support for this draft.
Document Quality
This document was developed by the WG over a two-year period. The
document is of good quality and is being implemented.
