Subject: Re: [pve-devel] seem than ifupdown2 is installed by default on upgrade (a friend reported me an ipv6 slaac bug)

Hi again,

I have reverified my ifupdown2,

In fact, I setup accept_ra=2  when interfaces is setup as "auto".  (but
not static or manual)


(as inet6 auto = slaac , it make sense to enable accept_ra).




But here, the non working setup is mixing "inet dhcp" + "inet6 auto"


"
auto vmbr2
iface vmbr2 inet dhcp
       bridge-ports eth0
       bridge-stp off
       bridge-fd 0

iface vmbr2 inet6 auto

"


Maybe  is it because ifupdown2 is merging interfaces, looking at debug
log, the "inet6 auto" is not catched.


For this setup, the working config is:


"
auto vmbr2
iface vmbr2 inet dhcp
       bridge-ports eth0
       bridge-stp off
       bridge-fd 0
       accept_ra 2
       autoconf 1
"
