This does not fix the problem.
The router with the public IP address sees the private IP as an IP that
is on its external interface. I believe this is due to the src-nat
that does nat for our 10.0.0.0/8 subnets - neighboring router has an IP
of 10.16.0.2/24.
I have not been having much luck with OSPF filters. I have another
segment on my network where I need to filter out 172.16.0.0/16 routes,
but the OSPF filters will not stop those routes from propagating.

If the problem is just that the public address occasionally sneaks through, you
could establish an ospf-in filter to filter out that public network. If the
problem is that the private address never shows up in OSPF, then that would
just be masking the symptom and not solving the problem.

I have come across an issue in a couple of places where a router that is
running src-nat and ospf barfs on OSPF because the source IP address for the
OSPF requests going across the private interface keeps coming up as a public IP
address.
I end up getting the message "Received packet from an unknown network" over and
over again. Is there a good way to prevent this from happening? My guess is that
setting up some IP Mangle rules that direct all traffic out the public interface that
matches the public network specification will do the trick. Any ideas?
