I support its publication. The document is well shaped to follow and is potentially a useful feature for scalable DC.

I too support the publication of this document.  The document seems well written.  Although I get nervous about features that can create loops if misconfigured, this is not a problem with using this feature for TRILL any more than using IS-IS for IP.  Since people seem to have it successfully deployed for IP, and find it useful, it should be equally useful for TRILL.

I think the draft is ready for publication.

This begins a 2 week WG LC on draft-ietf-trill-multi-topology-04.txt.

During this WG last call please include comment on the following three

things in addition to your normal comments:

1)      Does this draft support the things you desire to support multiple

topology routing of unicast and multi-destination traffic in TRILL?

[RP]: Yes.

 2)      Do you think this draft is read for publication?

[RP]: Yes, quick look-through, seems correct.

3)      Do you think that multi-topology trill has a place in the data

center deployments of TRILL?

[RP] Yes.
