> CPU/RAM overhead is insignificant with a bgpd like BIRD or Quagga. They work for internet-scale routing (currently over 610,000 prefixes) with trivial load. An Atom C-series with a few GB of RAM can deal with internet BGP routing updates (CPU becomes significant for packet forwarding, not so much maintaining routing tables). We've got a DPDK-enabled VRouter that will run over 12Mpps on a C2758 (8 core) with a full BGP table. |
