Version 5 was published on May 28, 2015. Authors have worked on adding applicability/use-case to the document, which clearly explains the rationale of this work. In the last IETF meeting there was quite a bit of support in the room. We are kicking off an adoption poll. Please share your support/concerns on this thread. Adoption poll will end on June 15th, 2015 @10am.

I have tried this on vario= us Cisco routers and it doesn't work. It complains about the interfaces= being in a different network.

Is this an implemen= tation flaw?

I am delighted to share that the authors of
draft-liang-ospf-flowspec-extensions and draft-shrivastava-ospf-flow-spec have merged their documents and it will retain the name
draft-liang-ospf-flowspec-extensions. Version 5 was published on May 28, 2015.

Authors have worked on adding applicability/use-case to the document, which=
clearly explains the rationale of this work.

In the last IETF meeting there was quite a bit of support in the room.

We are kicking off an adoption poll. Please share your support/concerns on<= br> this thread.

Adoption poll will end on June 15th, 2015 @10am.

Regards,
-Abhay

It is the Link State Request / Update exchange described mostly in section 10.9 . The main issue is that LSREQ packets often contain more LSRs that can be answered in one LSUPD packet and the fact that there is no explicit way how to see match LSUPD packets are proper responses to LSREQ packets. There are generally two approaches to this: (1) Router A sends LSREQ packet. When it is received by router B, router B immendiately answers with multiple LSUPD packets covering all LSRs. When router A receives LSUPD packet, it removes appropriate LSRs from Link State Request List, but only if all LSRs sent in the last LSREQ packet were removed then the next LSREQ packet is sent. (2) Router A sends LSREQ packet. When it is received by router B, router B immediately answers with just one LSUPD with just enough LSAs to fit to one LSUPD packet. When router A receives LSUPD packet, it truncates the Link State Request List and immediately sends the next LSREQ packet. RFC 2328 10.9 is a bit vague w.r.t. this issue, some sentences suggest interpretation (1), while others suggest (2). Example in RFC 2328 10.10 suggests (2) as it contains just one LS Update after LS Request, but that may be just ommited detail. Approach (2) also has a problem that it cannot distinguish LSUPD that is a reaction to LSREQ from some random asynchronous LSUPD that incidentally covers the beginning of the Link State Request List. We saw both approaches used in existing OSPF implementations. Unsurprisingly, mixing them causes some strange problems.

Consider an example. We receive the following set of SRGB ranges: 20000-22000 21000-24000 26000-28000 In such a case no one would consider using any of the ranges because the fi= rst two overlap - and using the third range (which does NOT overlap) is li= kely to be wrong because indices less than 4000 seem like they should be in= to one of the first two ranges - but we can't really be sure because we don= 't know which of the three ranges was misconfigured. Now, here is a second case: 26000-28000 20000-22000 21000-24000 Here, again, we don't know which of the three ranges is misconfigured - but= because it is the first range which does not conflict you want us to assum= e that it must be correct. We actually have no more reason to believe it is= correct than we did in the first case - but because it is the first range = you propose that we trust it. Now, the second case "might" be less ambiguous if we had some history - for= example, suppose the same router had previously advertised: 26000-28000 20000-22000 Then it advertised the third range (in conflict w second range) shown above= . With this history we "might" feel more strongly that the misconfiguration= was associated w adding the third range and so it is safe to use the first= range. But in the absence of history we really don't know which of the ran= ges should be considered valid - we are just hoping that the config error (= or implementation bug) is confined. Now, if you want to bring "history" into the specification, things become l= ess predictable because it is possible that a recently booted router won't = have the history - and so now all routers won't agree on what should be use= d and what should not. This is an example of how complex things can get when we try to define rule= s about how to deal with a set of information which is in error. This is wh= y, though I appreciate your desire to try to preserve what you hope is usab= le, taking a simpler approach (ignore) is appealing.=20 Les > -----Original Message----- > From: OSPF [mailto:ospf-bounces@ietf.org] On Behalf Of > bruno.decraene@orange.com > Sent: Thursday, June 25, 2015 6:58 AM > To: Stefano Previdi (sprevidi); isis-wg@ietf.org list > Cc: ospf@ietf.org > Subject: Re: [OSPF] How to handle multiple overlapping SRGB ranges >=20 > > From: Isis-wg [mailto:isis-wg-bounces@ietf.org] On Behalf Of Stefano > > Previdi (sprevidi) > > > > All, > > > > there's an open question that requires the wg to agree > > > > The issue here is related to SRGB ranges advertised within the SR-Cap > SubTLV. > > > > The question is: what a receiving router should do when receiving SRGB > > ranges that overlaps ? >=20 > Presumably, the question is equally applicable to OSPF, so I'm adding the > ospf WG in the discussion. >=20 >=20 > > Knowing that the spec mandates a single SR-Cap SubTLV, the overlap may > > happen only within the same SR-Cap subTLV and therefore it is clearly > > a local misconfiguration or an implementation bug in the router > > originating the SR- Cap. > > > > Personally, I would recommend to ignore the whole SRGB (not only the > > overlapping ranges) from the faulty router.

Sure. I'm all for the specification.

I propose to accept the SRGB descriptors until there is a problematic one. There is no issue with the first SRGB ranges. There is no reason to believe= that the originator is not capable of doing the sum (SRGB+index) and progr= am the result in its MPLS ILM (Incoming Label Map).=20 =20 > Now, the second case "might" be less ambiguous if we had some history - f= or > example, suppose the same router had previously advertised: >=20 > 26000-28000 > 20000-22000 >=20 > Then it advertised the third range (in conflict w second range) shown abo= ve. > With this history we "might" feel more strongly that the misconfiguration= was > associated w adding the third range and so it is safe to use the first ra= nge.

This is wh= y, > though I appreciate your desire to try to preserve what you hope is usabl= e, > taking a simpler approach (ignore) is appealing. _You_ changed the proposition to make it complex by introducing history. Again, let's discuss the proposition on the table. In term of complexity: In both propositions you need to - parse SRGB descriptor, presumably in order. - detect inconsistency between SRGB descriptors. - log the error a) With my proposition, you stop the SRGB parsing here and do nothing else. b) With your proposition, you need to roll back and remove previous SRGB de= scriptor. It's not clear to me why "a" (i.e. do nothing) is more complex than "b" (ro= ll back). Now, it would be good to also discuss the impact on the customer traffic of= both approaches: - if the node is considered non SRGB capable, all traffic for all FEC cross= ing that node is dropped. In a MPLS VPN network where all traffic is MPLS, = this is a big impact - if we only disregard the problematic SRGB descriptors, we save part of th= e traffic. How much of the traffic is purely hypothesis dependent. However = as the spec recommend (SHOULD) to add new SRGB descriptor at the end, typic= ally all existing traffic would be unaffected. So in summary, using the valid SRGB descriptors: - brings no issue - is equally simple - provides a significant protection of existing traffic. Indeed, some existing implementation may need to be touched, but the change= does not bring interoperability issue (compared to the previous one on thi= s subject, at least for IS-IS) /Bruno =20 > Les >=20 > > -----Original Message----- > > From: OSPF [mailto:ospf-bounces@ietf.org] On Behalf Of > > bruno.decraene@orange.com > > Sent: Thursday, June 25, 2015 6:58 AM > > To: Stefano Previdi (sprevidi); isis-wg@ietf.org list > > Cc: ospf@ietf.org > > Subject: Re: [OSPF] How to handle multiple overlapping SRGB ranges > > > > > From: Isis-wg [mailto:isis-wg-bounces@ietf.org] On Behalf Of Stefano > > > Previdi (sprevidi) > > > > > > All, > > > > > > there's an open question that requires the wg to agree > > > > > > The issue here is related to SRGB ranges advertised within the > > > SR-Cap > > SubTLV. > > > > > > The question is: what a receiving router should do when receiving > > > SRGB ranges that overlaps ? > > > > Presumably, the question is equally applicable to OSPF, so I'm adding > > the ospf WG in the discussion. > > > > > > > Knowing that the spec mandates a single SR-Cap SubTLV, the overlap > > > may happen only within the same SR-Cap subTLV and therefore it is > > > clearly a local misconfiguration or an implementation bug in the > > > router originating the SR- Cap. > > > > > > Personally, I would recommend to ignore the whole SRGB (not only the > > > overlapping ranges) from the faulty router.
