This probably means that the standby member is receiving traffic from
elsewhere that it forwards upon receiving it because it has a connected
route. You should be able to tell from where it comes by looking at the
source IP addresses.
You're correct. Due to the nature of the topology, I can't get rid of
the asymmetric routing at least for now.
The interesting thing, is that SOME macs are learned and some are not.
Increasing the mac aging helped quite a bit, but there's still a
problem.
I'm curious if my copp default is limiting ARP.
