MTU mismatch with nbr

We are running BIRD and BIRD6 to manage our BFD and OSPF relationship on our DNS servers. We moved the DNS servers onto a Fortigate firewall. I was able to get the BIRD daemon running, but BIRD6 is complaining about an MTU mismatch with the neighbour. Is there any way to tell BIRD to ignore the MTU? The OSPF status is showing the neighbour is in the Exchange state.
