OK looking at the generated keepalived.conf I suspected the nodes were using
different Neutron versions. Yes, this could have an impact.

I'd install them via the same tool, make sure the outcome is the same Neutron
code on both nodes with the same patches applied, recreate the routers entirely
and see what happens. If it works, work from there.
