Hi,
I posted a few hours ago in freebsd-questions a problem that seems very
similar to yours ("promiscuous mode / strange ethernet packets duplication
problem"). I too have Zebra running on my machines.
Have you checked that the ethernet interface of your B machine is not
in promiscuous mode for an unknown reason ?
We have several FreeBSD 4.7 boxes that automatically put all their
interfaces into promiscuous mode during the boot process. Does anybody
knows how to prevent that from happening ?
Regards
Yann
