Now I'm not clear what you meant by "almost all these messages are saying
whatever IP is going from or to a Cisco device". Are you claiming
that these MAC addresses belong to a Cisco device?
I mean that the list of machines that are associated with this error, either
the "from" or "to" part, are a single Cisco device, probably the router, but I
can't be sure. The MAC addresses being advertised are owned by the
Cisco device.
So I have errors like this:

all the "00:e0:b0..." entries are from a single cisco device. IN this series
it's all the second device. Later in the day there will be a mirrored series
where the "from" entry is that same cisco device.
Well it would be really good to know if "the Cisco device" was your
router (which would be very odd) or a switch. If the latter, it's
simply misconfigured for your network architecture. Contact your
Cisco Network Engineer.
