Subject:   slaac ipv6 bridge not working
Message-ID:  <20230208211213.64009129@cervin>

next in thread | raw e-mail | index | archive | help
Hi All,
     I am trying to configure a bridge with one real network interface and=
 one
tap interface (to make a virtual machine run with behyve).

Before the real network interface was added to the bridge, slaac was worki=
ng correctly (on the
device of the real interface). Once the interface is added to the bridge s=
laac does not
work anymore (on the bridge interface).

However, it is possible to add an IPv6 address manually on the bridge. The=
 command
"ifconfig bridge0 inet6 accept rtv_adv" succeed (return code 0) but
the address is not set. The command "rtsol -d bridge0" return a strange
message about "failed capabilities".

All the other parameters in the file /etc/rc.conf have not been changed bu=
t
the bridge is built in a script and not defined in the file /etc/rc.conf.

Do you have some ideas about the causes of this problem?

Thanks for your help,


regards
