We have CoPP deployed, but it is not that restrictive today (since our
v4 OSPF uses authentication).

Most of our setups use Ethernet with the "network point-to-point"
command since the routers are directly connected. Can you provide a link
about the unicast OSPF neighbor relationship/configuration? My searching
skills are failing me.
