Sure. Thanks! From: Zafar Ali (zali) [mailto:zali@cisco.com] Sent: Wednesday, July 23, 2014 3:51 AM To: Khuzema Pithewan; CCAMP (ccamp@ietf.org) Subject: Re: [CCAMP] draft-ietf-ccamp-lsp-diversity-04 Hi Khuzema: Yes, exclusion is signaled using XRO. We can add some text on crankback, as suggested by you. Thanks Regards ... Zafar From: Khuzema Pithewan <kpithewan@infinera.com<mailto:kpithewan@infinera.com>> Date: Wednesday, July 23, 2014 3:10 AM To: zali <zali@cisco.com<mailto:zali@cisco.com>>, "ccamp@ietf.org<mailto:ccamp@ietf.org>" <ccamp@ietf.org<mailto:ccamp@ietf.org>> Subject: RE: [CCAMP] draft-ietf-ccamp-lsp-diversity-04 Thanks. The issue is if XROs are not used in option#1, it relies on crankbacks only. So XROs are kind of mandatory for option#1 to work in reasonable way. Khuzema From: Zafar Ali (zali) [mailto:zali@cisco.com] Sent: Wednesday, July 23, 2014 3:03 AM To: Khuzema Pithewan; CCAMP (ccamp@ietf.org<mailto:ccamp@ietf.org>) Subject: Re: [CCAMP] draft-ietf-ccamp-lsp-diversity-04 Khuzema: We can add a Recommendation section to the draft. Option 1 also uses XRO. I did not get your comment. Thanks Regards ... Zafar From: Khuzema Pithewan <kpithewan@infinera.com<mailto:kpithewan@infinera.com>> Date: Monday, July 21, 2014 4:39 PM To: "ccamp@ietf.org<mailto:ccamp@ietf.org>" <ccamp@ietf.org<mailto:ccamp@ietf.org>> Subject: [CCAMP] draft-ietf-ccamp-lsp-diversity-04 Authors : It will be useful to have a recommendation section in draft to clarify which options can be used in what scenario. Some discussion on comparison /critique of options would help. For example : Option#1 has scalability issue if XROs are not used resulting in crankbacks one after another. So if client layer cannot provide XROs, option#2/3 should be used. Thanks Khuzema
