It may be difficult to keep the overview o= f the solution complete and up-to-date as well. 4/ Sec 3.1 and Sec 3.3: Should we consider s/Traditional BFD/BFD [RFC5880]/= since the latter seems more accurate in my opinion.

This draft is a work item of the Bidirectional Forwarding Detection Working Group of the IETF. Title : Seamless Bidirectional Forwarding Detection (S-BFD) Authors : Nobo Akiya Carlos Pignataro Dave Ward Manav Bhatia Santosh Pallagatti Filename : draft-ietf-bfd-seamless-base-04.txt Pages : 21 Date : 2015-01-12 Abstract: This document defines a simplified mechanism to use Bidirectional Forwarding Detection (BFD) with large portions of negotiation aspects eliminated, thus providing benefits such as quick provisioning as well as improved control and flexibility to network nodes initiating the path monitoring. This document updates RFC5880. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-seamless-base/ There's also a htmlized version available at: http://tools.ietf.org/html/draft-ietf-bfd-seamless-base-04 A diff from the previous version is available at: http://www.ietf.org/rfcdiff?url2=draft-ietf-bfd-seamless-base-04 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

is a small working group, it'd be good to get further feedback.

Authors, now is a great time to rally people to *read* this draft and
provide feedback to the Working Group.

Thanks Marc for your reply.


I u= nderstand that we can use one knob to turn on/off the Echo advertisement (n= on zero value in echo-rx).

But I have 2 options regarding= what should be my response to the advertisement.

1. I ca= n ignore the advertisement by not sending my echo packets to be looped back= by advertiser
2. I can accept (honour) advertisement by send= ing my echo packets to advertiser.

Now my question is, do= es RFC mean that we need another knob to control the options stated above?<= br>
I think RFC is not clear on this aspect.

Indeed, from RFC 5880, section 3.2:

=C2=A0 =C2=A0The Echo function may be enabled individually in each directio= n.=C2=A0 It

And section 6.8.9:

=C2=A0 =C2=A0The transmission of BFD Echo packets is otherwise outside the = scope
=C2=A0 =C2=A0of this specification.

The RFC does not exclude this option and I guess that is what most
implementations do - they have a config knob to turn on/off echo. If you co= me
up with a different mechanism you are free to implement it.

I assume you understand that "honors the advertisement or not" is= only an
option when the peer sends control packets with the "Required Min Echo= RX
Interval" field being non-zero. In case the field is zero ...

=C2=A0 =C2=A0 =C2=A0 If the Required Min Echo RX Interval field is zero, th= e
=C2=A0 =C2=A0 =C2=A0 transmission of Echo packets, if any, MUST cease.

... you must stop sending echo; there is no option to honor or not.


Best regards,
Marc

The situation is really not much different than async mode. In async, we negotiate the max rate at which we wish to receive packets. If a sender violates that, BFD can't do much about it. It's a form of DoS if you want to look at it that way. Similarly for echo, if a sender sends the packets too fast, the receiver will have to deal with it. The difference of course is in the response. In async, the receiver itself has negotiated the sending rate in the other direction. It need not be a bad actor if the other party is. In the case of echo, there are two likely outcomes: - The device providing echo services requests a given rate to provide a level of fairness or resource control. If echo packets come in too fast, then they *might* still get looped. They may be dropped, but mostly due to resource exhaustion. - The device may implement a rate limiter to proactively control the echo responses. The implementation is free to choose whatever it wants to. -- Jeff From nobody Wed Jan 28 14:47:05 2015 Return-Path: X-Original-To: rtg-bfd@ietfa.amsl.com Delivered-To: rtg-bfd@ietfa.amsl.com Received: from localhost (ietfa.amsl.com [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id EAB681A1B05 for ; Wed, 28 Jan 2015 14:46:59 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -114.511 X-Spam-Level: X-Spam-Status: No, score=-114.511 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, RCVD_IN_DNSWL_HI=-5, SPF_PASS=-0.001, T_RP_MATCHES_RCVD=-0.01, USER_IN_DEF_DKIM_WL=-7.5, USER_IN_WHITELIST=-100] autolearn=ham Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id tJH2QzPt5RVz for ; Wed, 28 Jan 2015 14:46:58 -0800 (PST) Received: from alln-iport-3.cisco.com (alln-iport-3.cisco.com [173.37.142.90]) (using TLSv1 with cipher RC4-SHA (128/128 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id D68151A1B03 for ; Wed, 28 Jan 2015 14:46:57 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=cisco.com; i=@cisco.com; l=1248; q=dns/txt; s=iport; t=1422485219; x=1423694819; h=from:to:cc:subject:date:message-id:references: content-transfer-encoding:mime-version; bh=YdxalVdk5JMp7squGRL/7TvNiV5EmsyjYJeAHmezowU=; b=Einaiw/Ge4+RQIu6Wfs8fiImDb5la7OWocjPtFgfj1TZYyeP2fsfQ6HZ bXafAShX+hueHAMF4zfcW2c6aI4yNT5pVZEy4RKaA/D0MaEGsnDjnOhAb yaUJx2/cF1sWFnhs8/LQU5yk3JPq4lCsid/u9iFBDZCJuzKCmIEB8Wi/e w=; X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: A0AlBQArZslU/5ldJa1agmQiUloDxFmFbwKBFkMBAQEBAX2EDAEBAQMBOj8FCwIBCCIUEDIgBQIEAQ0NiBwIAQzWKAEBAQEBAQEBAQEBAQEBAQEBARqPRzGDHYETBY0TgWGDS4ckkHkig26CM34BAQE X-IronPort-AV: E=Sophos;i="5.09,483,1418083200"; d="scan'208";a="118466401" Received: from rcdn-core-2.cisco.com ([173.37.93.153]) by alln-iport-3.cisco.com with ESMTP; 28 Jan 2015 22:46:58 +0000 Received: from xhc-aln-x07.cisco.com (xhc-aln-x07.cisco.com [173.36.12.81]) by rcdn-core-2.cisco.com (8.14.5/8.14.5) with ESMTP id t0SMkvcZ002751 (version=TLSv1/SSLv3 cipher=AES128-SHA bits=128 verify=FAIL); Wed, 28 Jan 2015 22:46:57 GMT Received: from xmb-aln-x01.cisco.com ([fe80::747b:83e1:9755:d453]) by xhc-aln-x07.cisco.com ([173.36.12.81]) with mapi id 14.03.0195.001; Wed, 28 Jan 2015 16:46:56 -0600 From: "Nobo Akiya (nobo)" To: Marc Binderberger , Sam Aldrin Subject: RE: Seeking opinions on draft-akiya-bfd-seamless-alert-discrim Thread-Topic: Seeking opinions on draft-akiya-bfd-seamless-alert-discrim Thread-Index: Ac//wAdQ8oS8wTAIRaCZduflS+eKRACnnpkAALMORiAAGw69AABIby4QAFSEnAAAB0lM4AAWZpcAAD0O34AAALf5AAx0cNYw Date: Wed, 28 Jan 2015 22:46:56 +0000 Message-ID: References: <20141125223733023799.7609dd07@sniff.de> Accept-Language: en-US Content-Language: en-US X-MS-Has-Attach: X-MS-TNEF-Correlator: x-originating-ip: [161.44.212.98] Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable MIME-Version: 1.0 Archived-At: Cc: "rtg-bfd@ietf.org" , "manav@ionosnetworks.com" X-BeenThere: rtg-bfd@ietf.org X-Mailman-Version: 2.1.15 Precedence: list List-Id: "RTG Area: Bidirectional Forwarding Detection DT" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 28 Jan 2015 22:47:00 -0000 > To summarize: > - I will spawn off a separate thread for the alert discriminator soon. Hello BFD WG, Finally getting around to follow up on this AI. http://datatracker.ietf.org/doc/draft-akiya-bfd-seamless-alert-discrim/?inc= lude_text=3D1 The document describes one simple extension: Let's make S-BFD discriminator= zero(0) to have a special meaning. The primary driver for this is to allow an S-BFD initiator to discover the = target S-BFD discriminator, by sending an S-BFD ping packet with your_disc= =3D0 and getting back a valid S-BFD pong packet with "my_disc=3D". In other words, when an S-BFD reflector receives an S-BFD ping= packet with your_disc=3D0, it processes it because S-BFD discriminator zer= o(0) has a special meaning. Motivation for using this approach to discover the target S-BFD discriminat= or is described in Section 2.1 of the document. I think it is most important to discuss this, thus let's leave out discussi= ons on other use of the S-BFD alert discriminator (i.e., Section 2.2) for n= ow. Personally, I think this is very useful extension to the S-BFD mechanism th= at we've been working on. I'm curious to see what others think?

Some implementations have a single knob that controls both the advertisement as well as the honoring. If you like to implement two knobs, one for advertisement and one for honoring - you are free to do so. > Now my question is, does RFC mean that we need another knob to control the > options stated above? > I think RFC is not clear on this aspect. To say the least :-) because it deliberately is not saying anything. Again, section 6.8.9 says: The transmission of BFD Echo packets is otherwise outside the scope of this specification.
