RE: Last Call: Traffic Engineering Extensions to OSPF Version 2 to Proposed Standard
... snip My recommendation against using this draft as the basis for building further TE-extensions to inter-area and mixed networks was in the context of OSPF Autonomous System (AS). I also mentioned the draft has scalability limitations in extending this to inter-area and mixed networks - also in the context of OSPF AS. Without going into the details of the Multi-area MPLS Traffic Enginering draft - The work cited in this draft as going on to address multi-area TE is in the MPLS signalling context, not in the OSPF. As I said in my previous e-mail quite a few scenarios described in draft-kompella-mpls-multiarea-te-03.txt are supported with the TE extensions that are subject to this Last Call. That is precisely while quite a few scenarios in the Multi-area MPLS Traffic Engineering draft do not require any additions to what is already defined in the katz-yeung draft. Yakov. Yakov, Yes, quite a few scenarios described in kompella-mpls-multiarea-te draft are supported with single-area TE extensions and do not require any additions. And, katz-yeung draft proposal will suffice for single-area TE extensions. katz-yeung draft does not cover dissemination of inter-area TE info (which I was refering to as *inter-area OSPF-TE*). Neither does the draft claim to do so. Inter-area OSPF-TE is a scenario described in kompella-mpls-multiarea-te for faster convergence in LSP computation. In this context - my recommendation to not use katz-yeung draft as the basis to extend to inter-area OSPF-TE was because of its scaling limitation. Neither katz-yeung nor kompella-mpls-multiarea-te drafts address mixed networks. katz-yeung draft has limitations with flooding disruption and topology isolation in a mixed network - both intra-area and inter-area. This was another reason why I recommended to not use katz-yeung draft as the basis to extend to inter-area OSPF-TE. regards, suresh
