I'm trying different network configurations between LXC containers to learn something and have fun.
I've just found out that two containers can communicate with just a veth pair, so I'd like to know from experts why all the tutorials show procedures that include a bridge in the host conected to the veth ends.
I though a simple veth pair could easily replace a MACvlan bridge mode where the host can't communicate with the containers.
Are there some security implications?
Whare are the real advantages of Linux Bridges and Open vSwitches with this configuration (only two namespaces)?
