Hi,

Since the TRILL active-active topic was proposed, we had been working on the solution using pseudonode nicknames and Affinity TLVs. In this draft, coauthors and contributors designed an alternative proposal.

We incorporated comments received from the f2f meeting, mailing list and offline discussions. With ESADI notification, remote RBridges can keep multiple MAC attachments in the LSDB hence the proposal requires no hardware modification. TLVs are specified for the control plane to make it complete and deployable. Now it's in a steady state and ready for call. Authors would like to request a call for WG adoption for this draft.
