Arjun, all, I confess that I don't know much about SIDR, but I guess that I'm not the only one in L3 VPN. Therefore clarification may be useful for the L3 VPN WG.
Let's assume that no RPKI is used. 1) Given that the goal is to protect from unintentional errors, can you elaborate on the added value brought by l3vpn-origination compared to the use of a (extended) community agreed upon the VPN sites (e.g. some kind of a shared password)? The latter being available now, how much is it deployed/used now? (I would assume that l3vpn-origination would be used by a subset of such current users) 2) Can you elaborate on how l3vpn-origination protects from unintentional errors by the legitimate originator? Seems to me that both correct and erroneous routes would be signed by the egress CE/PE and hence accepted by the ingress. 3) Given that a VPN may want to import routes from outside of the VPN (e.g. provider IP services (e.g. voice gateway), extranet), how does l3vpn-origination protect from unintentional errors from those partners? Thanks for the clarifications, Bruno _________________________________________________________________________________________________________________________ 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.
