Document: draft-ietf-lsr-isis-area-proxy-10 Reviewer: Peter Yee Review Date: 2023-12-26 IETF LC End Date: 2023-12-22 IESG Telechat date: 2024-01-04 Summary: This is an experimental addition to IS-IS routing to allow the use of Level 1 networks for transit of Level 2 network traffic without burdening the Level 2 networks with full knowledge of the Level 1 network topology. At least I think that's what this document covers. Routing is far outside of my wheelhouse, so I can't really provide any routing-aware comments despite some time spent glossing over some of the normative references. There are a few truly minor nits in the document. [Ready with nits] Major issues: None Minor issues: None Nits/editorial comments: Page 4, second paragraph, second sentence: change "MPLS based" to "MPLS-based". Page 4, section 1.1: in the text version that I read, the boilerplate contains the link "(https://tools.ietf.org/html/bcp14)". While this is found as a hyperlink in the PDF and HTML versions, I don't believe it should appear in the text version. I don't know if this is a tool issue, but recent RFCs that I downloaded did not contain it. The hyperlink appears to cause idnits to complain about incorrect boilerplate text. Page 6, 1st paragraph, 1st sentence: change "i.e. Ethernets" to "i.e., Ethernets", which is to say, change the first space to a comma. Page 9, last paragraph, last sentence: change "implementation-dependent" to "implementation dependent".
