[lxc-users] multiple containers on the same vlan

[Genco Yilmaz]

Hi,
   When I try to configure two containers which need to be on the same vlan
lxc-start complains as expected. I believe this is an expected error.
Is there any way to link multiple containers without using softbridge+veth
pair
by using network.type vlan? or what is the best practice in this type of
topology?

thanks.
