It is described in the following quotation from the shell script used to create and activate the bridge. #By default and even, if in the file "/etc/rc.conf" #the variable 'ipv6_activate_all_interfaces=3D"YES"' #is defined, the interface will be created with IPv6 #disabled. No local-link address is generated #and thus no IPv6 networking is possible. ifconfig bridge0 inet6 -ifdisabled ifconfig bridge0 inet6 auto_linklocal ifconfig bridge0 inet6 accept_rtadv best regards On Wed, 8 Feb 2023 21:12:13 +0100 Pierre Dupond <76nemo76@gmx.ch> wrote: > Hi All, > I am trying to configure a bridge with one real network interface a= nd one > tap interface (to make a virtual machine run with behyve). > > Before the real network interface was added to the bridge, slaac was wor= king correctly (on the > device of the real interface).
