- <MY INITIAL COMMENT> Section 5.1 1. For FEC128 PW, the PW with the lowest pw-id value is selected. 2. For FEC129 PW, each PW in a redundant set is uniquely identified No idea what FEC128 and FEC129 were. I had to search and found http://tools.ietf.org/html/rfc4379#section-3.2.8, where by the way, they're spelled "FEC 128" and "FEC 129". So please add a reference. </MY INITIAL COMMENT> You solve the issue in section 5.1 by removing FEC128 and FEC129, but FEC 128 and FEC 129 still appear in different places of the document

Thank you with your patient work to address my Discuss. --- I continue to be disappointed by the piecemeal invention of bolt-on signaling features for PW management. It really seems that the working group needs to work on a functional architecture for pseudowires to work out all of the bits and pieces that are needed for redundancy, bandwidth, multi-segment routing, etc., etc. I wish this would happen before we incrementally munge the protocol too much, but I understand that this is not directly actionable for the authors of this document.

The security considerations say that this is the same as for 4447, which is arguably correct, but 4447 really defers to 3036, which a) doesn't consider switching over to a "less good" PW as a potential DoS (is it?) and b) only has TCP-MD5 based security which even in 2001 attracted an IESG note, repeated in 3036 from rfc 2385 (from 1998!). Any chance of getting some 21st century security stuff done in PW-land? (Sorry, but that's hard to resist:-) This is probably not the place to fix that, but it'd be good to know if there's a plan. Is there? Nits: - PE-rs is used without expansion (on p2) - FEC128 and FEC129 are used without definition on p11 (As as AGI::SAII:TAII) - What is the "system IP address"? (on p11) Could be fairly obvious, but then again if a node has many addresses, maybe not.

Please consider the issues raised in the Gen-ART Review by Miguel Garcia on 23-May-2012. I tend to agree with his points on RFC 2119 language in Sections 5 and 15. Please find the review at: http://www.ietf.org/mail-archive/web/gen-art/current/msg07447.html.

Section 2: MANDATORY OPTIONAL OPTIONALLY Neither MANDATORY nor OPTIONALLY are 2119 terms. I suspect that the capitalized words in this section are a new magical usage of which I am unaware. Perhaps you might like to define terms? 5.1 The PW endpoints MAY also implement the following optional active PW selection mechanism. 1. If the PW endpoint is configured with the precedence parameter on each PW in the redundant set, it MUST select the PW with the lowest configured precedence value. So you MAY do something that you MUST do? I am confused. a management indication SHOULD be generated I may not understand what is meant by a "management indication" here, but it sounds like an implementation choice, not something that is required for interoperation. Did I get that wrong?

Note these comments are the same for both draft-ietf-pwe3-redundancy and draft-ietf-pwe3-redundancy-bit. Much of the Terminology is repeated in draft-ietf-pwe3-redundancy and draft-ietf-pwe3-redundancy-bit. Can't you just point from on to the other? This uses the TCP MD5 "signature" option [RFC5036]. KARP's hopefully going to get this fixed sooner rather than later. So there's nothing for the authors to do about this otherwise recurring gripe. I'd like to suggest some tweaks to the security considerations section, assuming of course that I've not totally missed the mark: 1st - I think the "LDP extensions" are referred to as options in both RFC 4447 and 5036? 2nd - I think there's only one of them? 3rd - I think you mean control plane not control protocol? How about the following tweaks to the security considerations section: This document uses the TCP MD5 Signature option, as specified in , to protect pseudowires. This document has the same security considerations as in the PWE3 control-plane . If you want to future proof the text more maybe: LDP extensions/options that protect pseudowires must be implemented because the security considerations for the bits defined in this document have the same security considerations as the PWE3 control-plane .
