Re: [bess] 答复: Flowspec for L2VPN and E-VPN

Hi Bertrand,
Yes, unified fs safi is a good design, the fs safi can be used for all kinds of BGP fs, like IPv4,VPNv4,IPv6,VPNv6, layer 2(EVPN,PBB-EVPN,TRILL-EVPN,NVO3-EVPN,VPLS,PBB-VPLS.etc).
Currently IPV4 and VPNv4 flowspec has already been defined in RFC [5575]. IPv6 and VPNv6 flowspec definition is a WG draft.
If we prefer unified fs safi, should layer 2 fs and IPv6 fs merge into one single draft or evolve separately? I would like to hear WG co-chairs and experts opinion on this point.
Thanks
weiguo

+1... Would to avoid to see multiplication of fs safi.
