--- Comment #1 from Jason Tubnor <jason@tubnor.net> ---
I run an OpenBSD PF firewall guest in bhyve with taps to various bridges and
IPv6 native on the firewall to the internet and internal machines. From an
internal machine, I achieve a 20/20 on ipv6-test.com and that wouldn't be
possible if there was an IPv6 issue in any chain of the FreeBSD
13.0-RELEASE/lagg/bridge/tap/bhyve/OpenBSD configuration.

I know it is possible to put IPs on bridge interfaces but have you tried
without this? I typically IP the interface from the host that is attached to
the bridge.

Can you post kldstat please?
