At least the comment says that it should not be default which implies that it used to be. If there is a logic error in the commit (I just noted the change to rtadv and the comment, but did not attempt to confirm the logic), perhaps accept_rtadv got turned off on more than just bridge interfaces. 564<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l564>; bridge[0-9]*) 565<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l565>; # No accept_rtadv by default on if_bridge(4) 566<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l566>; # to avoid a conflict with the member 567<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l567>; # interfaces. 568<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l568>; return 1 569<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l569>; ;; 570<http://svnweb.freebsd.org/base/stable/9/etc/network.subr?annotate=253683#l570>; *) -- R.
