    Hi,

      I recently made a test bridging a few VLAN interfaces under FreeBSD
    5.2-REL and ran into some unexpected issue: some packets coming from one
    vlan inteface with destination MAC on another vlan would pass in the
    parent VLAN interface, but didn't make it into the child vlan interface,
    as seen by tcpdump'ing on both of them. Like the packet was eaten before
    it made it into the child vlan interface. Activating the debug code
    shows that neither the bridge fordwarding routine wasn't catching the
    packets.

      All vlans were child of the same parent interface (a RealTek) and they
    were all configuren in the same bridge cluster. Either with configured
    IPs or without (just up'ed the intefaces).

      I might have botched the interfaces by mutiple reconfigurations, but I
    just would like to know if other people had success with bridged VLAN
    interfaces (yes, it sounds a bit weird if you think of it :) ).
