We sell IP transit to some smaller ISPs and also offer High Speed to residential clients and our current Router solution is reaching the limit, I would like to deploy a new Mikrotik Router for 40Gbps of traffic. I don't consider the CCR1072 because it only has 10Gbps ports and I'm considering 40Gbps ports now. It needs to handle 4 full BGP tables and some BGP filters. What solution could you suggest me for that kind of setup?
The best Mikrotik device i would recommend for your needs its called "Juniper MX104" it will suit you just fine up to 160gbps, if you require anything further then 160gbps backhaul i recomend the "Juniper MX240" and be happy.
in the past i have done some testing with with some X64 AMD octa core overclocked 4.0ghzp cpus running Mikrotik RouterOS x86/64 enabled, the max troughput i managed to run on the internal cpu core was abour 25gbps on udp and litle over 11gbps TCP..
not shure how it woudl behave on one Dell PowerEdge 6100 series with 48 cores total from all 8 cpus.. with 192GB RAM.. not shure if it would even be detected correctly as on the PC i runned i had 16GB of ram and only 6GB were detected.. i think there is some old post of mine with the pictures of the benchmark tests.
now putting that aside testing is one thing, real day to day job task , with bgp routing, nat, pppoe and so on.. it another completely differente story.
