Bridging multiple interfaces instead of using a hub/switch

  • What disadvantages to bridging multiple interfaces to a single broadcast domain are there.  2 or more interfaces for LAN etc.

    Thanks in advance

  • Performance. All that traffic hits the CPU/OS and also needs to pass on the PCI/PCIe bus. You'd be hard pressed to get anywhere close to the performance of a real switch (in bandwidth, latency, pps or pretty much any other metric) - but if it's useful in your application (bridging firewall or whatnot) it does work.
