Dear Donald,

Sorry for the delay, I set up a test lab with latest OPNsense and FRR 
7.4, but with real interfaces it seems to work.
I can not reproduce with full-table and WireGuard interfaces, maybe it's 
related to the interface type of WG (tun).

I try to invite the author of the problem to join here.

Best,
Michael
