Hi all, As part of the discussions during the OSPF WG meeting, the following comes imho as the bottomline of the discussion for what concerns TTZ: what is the potential gain
i) when TTZ is used as "replacement of" existing OSPF techniques (thus compared to multi-area/ABR) ii) when TTZ is used "in complement to" OSPF techniques (thus in addition to) The answer should help determining whether current multi-area/ABR is "too heavy for what it brings" vs there is a "third routing level" required in OSPF to sustain large deployments. In the latter case, assuming that multi-area/ABR is still appropriate, the next question would be: is it more suited to look at different mechanism or re-use as much as possible the existing one e.g. "sub-ABR" ? Opinions ? Comments ?
