Hi working group, We have a new working group document. Authors, can you please repost as draft-ietf-bess-bgp-vpls-control-flags ? Thank you, -Thomas/Martin 2015-10-26, Ravi Singh: > Hi Thomas, Martin >> Before adopting this draft, we would like hear people actually experiencing pain >> related to not solving this issue and hear about implementations in actual >> products. > > In a network where some BGP-VPLS PEs have ability to insert CW and some do not, not implementing section 3 has potential to cause the PW to not come up or cause dropped packets (depending on implementation). > Section 3 of this draft is implemented in JunOS. See last paragraph on > http://www.juniper.net/techpubs/en_US/junos14.1/topics/concept/vpls-bgp-control-word-overview.html > This was implemented in response to a specific-network-deployment-issue. > > The key aspect of RFC4761 that necessitates the text of section 3 of this draft is that the NLRI-advertising-PE is predicating on all other PEs in the same VPLS, that they must or must-not insert the CW, for example, regardless of whether they have the capability or not. [See https://tools.ietf.org/html/rfc4761#section-3.2.4] > This is in contrast to the proposed modification (for a different purpose) where this PE is just advertising its ability (https://tools.ietf.org/html/draft-ietf-bess-fat-pw-bgp-00#section-2) > > The proposed text in section 3 provides a way around presumption of other-PEs' abilities. > Section 4 provides an extension of the same intent for a deployment where the transport LSP maybe a p2mp LSP. > Section 5 generalizes the previous sections as deployed to multi-homing scenarios. > > Both p2mp and multi-homing have some deployments and may run into the issue. > > Regards > Ravi > > > >> -----Original Message----- >> From: thomas.morin@orange.com [mailto:thomas.morin@orange.com] >> Sent: Monday, October 5, 2015 12:29 AM >> To: bess@ietf.org; draft-singh-bess-bgp-vpls-control-flags@tools.ietf.org; Ravi >> Singh <ravis@juniper.net>; Kireeti Kompella <kireeti@juniper.net>; >> senad.palislamovic@alcatel-lucent.com >> Subject: Re: [bess] Poll for adoption: draft-singh-bess-bgp-vpls-control-flags >> >> Authors of draft-singh-bess-bgp-vpls-control-flags, working group, >> >> The support base for this proposal is not large. >> Before adopting this draft, we would like hear people actually experiencing pain >> related to not solving this issue and hear about implementations in actual >> products. >> >> Let's consider this poll for adoption open until we hear more. >> >> Best, >> >> Thomas/Martin >> >> >> thomas.morin@orange.com : >>> Hello working group, >>> >>> This email starts a two-week poll on adopting >>> draft-singh-bess-bgp-vpls-control-flags-01 [1] as a working group item. >>> >>> Please send comments to the list and state if you support adoption or >>> not (in the later case, please also state the reasons). >>> >>> This poll runs until **September 29th**. >>> >>> >>> *Coincidentally*, we are also polling for knowledge of any IPR that >>> applies to this draft, to ensure that IPR has been disclosed in >>> compliance with IETF IPR rules (see RFCs 3979, 4879, 3669 and 5378 for >>> more details). >>> >>> ==> *If* you are listed as a document author or contributor please >>> respond to this email and indicate whether or not you are aware of any >>> relevant IPR. >>> >>> The draft will not be adopted until a response has been received from >>> each author and contributor. >>> >>> If you are not listed as an author or contributor, then please >>> explicitly respond only if you are aware of any IPR that has not yet >>> been disclosed in conformance with IETF rules. >>> >>> Thank you, >>> >>> Martin & Thomas >>> bess chairs >>> >>> [1] >>> https://tools.ietf.org/html/draft-singh-bess-bgp-vpls-control-flags >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> >>> >>>
