Zhibo – Following up on Acee’s comment…he is (of course) quite correct that there already is a per link MTU sub-TLV defined by RFC 7176 – it is sub-TLV 28 defined here: https://www.iana.org/assignments/isis-tlv-codepoints/isis-tlv-codepoints.xhtml#isis-tlv-codepoints-22-23-25-141-222-223 In reading your draft, it seems that what you want to advertise is a per link attribute – not a per node attribute – in which case the existing sub-TLV is a perfect fit. Not at all clear why we would need a new TLV – nor how such a TLV would allow you to advertise a per-link attribute without repeating all of the context information (neighbor ID, link endpoint identifiers) already available in TLVs 22, etc. Do you agree that IS-IS already has what is needed and therefore does not need any additional protocol extension?

As LSR is one of the most popular WGs, you need to get your requests in early. With respect to this draft, there is already an IS-IS sub-TLV MTU advertisement defined in RFC 7176. While the RFC is specific to TRILL, I don’t see any reason why the sub-TLV couldn’t be used in non-TRILL deploymennts.
