Member interfaces of a bridge device should not accept route advertisements from the router on the segment; only the bridge device itself should. Right now, to get ipv6 bridges to work properly, this setting has to be manually set in sysctl.conf. If it is not set, the routes acquired by the member interface will pollute the routing table and break ipv6 connectivity. Reproducible: Always

This likely needs work to do the same thing on BSD.
