Hi,
I don't use 11.0 neither 12.0, but on 12-stable and I don't reach to
reproduce this opsf6 problem.
I've tested different setups documented here:
https://bsdrp.net/documentation/examples/simple_bgp-rip-ospf_lab (with
virtIO and em emulated NIC).
https://bsdrp.net/documentation/examples/maximum_bsdrp_features_lab (with
em emulated NIC)

Do you have specific configuration on your interface, like non-default MTU
or other ?
