Pardon my ignorance, can you explain why you set an IPv4 address on your
bridge and an IPv6 address on your bridge interfaces?
I wondered the same.
It's simple, although isn't obvious from this abridged example.
No it's not.
I need a single IPv4 for both interfaces, so I set it on a bridge.
I don't need distinct IPv4 on ports, so I don't set it there.
This has nothing to do with IPv6 config.
Bridged interfaces retain their MACs, so they would get different IPv6
ULAs, which are provided by radvd from the different host.
Not if they are bridged before they are brought UP or accept_ra/autoconf
is disabled.
And get myself all kinds of unneeded trouble, or I can do:
allow-br0 eth0
iface eth0 inet6 auto
autoconf 0
accept_ra 0
ovs_type OVSPort
ovs_bridge br0
Ok, THIS, provides the missing info from your previous post : disable
autoconf and accept_ra.
But according to man interfaces(5), the inet6 "auto" method ignores the
"autoconf" option. This option is specific to the "static" method.
