Hi Peter, http://www.aristanetworks.com/media/system/pdf/Datasheets/7050S_Datasheet.pd... Arista 7050S-64 48 x 10GE + 4 x 40 GE, price around 25k$ in gpl. Large buffers, supports MLAG, DCB, wire-speed L2/L3 (OSPF,BGP), but doesn't have any kind of TRILL implementation. Have it in production, but for now using for L2 only with MLAG. As option also can be considered: Brocade VDX6720, has own TRILL-like protocol to make STP-free topology, also can do L3, DCB but pay attention licensing is painful with Brocade. Best Regards,Sergey

Well, talking about HP´s A5920/A5900 series. Last time I was looking, their virtual routing instances haven´t supported IPv4 multicast, nor IPv6 multicast/unicast, nor any policy based routing.
