Hello Authors, Please find below my comments/suggestions on this draft. I am sharing them upfront given the packed LSR agenda.
1) Sec 3 the rationale provided for not using the Inter-AS TE LSAs/TLVs is not sound in my opinion. I would say that the TE encoding may not be suitable for use in all deployments as their advertisement results in the addition of those Inter-AS links in a TE topology database and that may not be desired. So, I would suggest that the draft keeps the option of use of Inter-AS TE TLVs valid and goes ahead with the Stub Link proposal as an alternative with broader applicability (also see the next comment). 2) For the proclaimed wider applicability (e.g., links to servers/hosts) in the slides, there is no such text in the draft. The draft seems focused on Inter-AS links. I hope the authors update either the draft or the slides - to be in sync with their objectives. 3) The use of the prefix TLVs in this context is something that is (in my opinion) broken from day 1 of this draft. Prefixes are for reachability. For identification of links, we have the local/remote link identifiers along with the local/remote IP addresses (NOT prefixes!). This to me is a NO-GO for the progression of this document. 4) The placement of the Stub Link TLV should be top-level (similar to other/existing links). I can share further suggestions offline, provided we reach an agreement on the above points and we converge on the main purpose/motivation for this work. Thanks, Ketan
