From the linked wiki page, did you also enable rtsold(8)?

Code: 
   6 sysrc rtsold_flags='-i -m bridge0'
   7 sysrc rtsold_enable='YES'

dear SirDice :
i have fellow https://wiki.freebsd.org/crest/the-correct-way-to-configure-bridges-in-freebsd-for-ipv6-and-ipv4 ... but i still not get stable ipv6 gateway for my bridge ....
if i want to ipv6 work normal . i need to configure a ipv6_defaultrouter="fe80::1$xxxxx" by manual..
if i configure ipv6 default gateway manuallly...i will get double gateway.. please see below inform.
Internet6:
Destination Gateway Flags Netif Expire
::/96 link#2 URS lo0
default fe80::1%public UG public
default fe80::1%public UGS public
::1 link#2 UHS lo0
 
Oh, right! I always forget about that one. I had to configure it for my fibre connection at home too.

Code: 
mpd_enable="YES"
netwait_if="ng0"
rtsold_enable="YES"
ipv6_cpe_wanif="ng0"
ipv6_defaultrouter="-iface ng0"
dhcp6c_interfaces="ng0"
rtadvd_enable="YES"
rtadvd_interfaces="em1.10 em1.11 em1.20"
DHCPv6 -> PPPoE -> VLAN -> physical interface
It was ridiculously complex setting this up, but I refuse to use that locked down router the ISP supplies 😁
 
Dear SirDice :
now my bridge was working . but new problem coming .... when i start vm or stop vm . the bridge will lost default router about 4 seconds...then autocome back....jesus.....
