From: [email protected] [mailto:[email protected]] On Behalf Of Robert Raszuk Sent: Friday, March 17, 2017 2:09 PM To: DECRAENE Bruno IMT/OLN Cc: Ben Maddison; [email protected] Subject: Re: [GROW] draft-ietf-grow-bgp-gshut status?
[Bruno] The benefit of using a well-known community is that everyone uses the same. Otherwise, the operator shutting down/reloading a node with 50 EBGP sessions would need to attach 50 different communities. Nope. You send only one .. the one you told your peers that means your g-shut. But to respect your peer's g-shuts you may end up matching on a few ... not that each VPN site will have it's own but your upstreams or peers sure could. [Bruno2] I hope that in the end, we’ll agree that using a single community for all EBGP sessions is just easier. But in the worst case, we don’t have to. Registration policy is FCFS and the g-shut community is already allocated. In any case as far as RFC 1997 there was big discussion in July and August of 2008 in IDR started by Dave on how to reserve new values. I do not recall what was the final outcome of that. https://mailarchive.ietf.org/arch/msg/idr/U6mR4hST3ZX-Ai5jyRKabhB9n8o [Bruno2] https://www.iana.org/assignments/bgp-well-known-communities/bgp-well-known-communities.xhtml Range [https://www.iana.org/assignments/_support/sort_none.gif] Registration Procedures [https://www.iana.org/assignments/_support/sort_none.gif] 0xFFFF0000-0xFFFF8000 First Come First Served 0xFFFF8001-0xFFFFFFFF Standards Action _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.
