<p>Is it possible to do this: say run flannel on node{1, 2, 3} and calico on node{4, 5, 6}. Obviously, pods can only communicate within the same <em>network</em>.</p>

<p>The short absolute answer is yes. Considering that overlays are speaking CNI and CNI is a standard and that you may have to hack the code in the overlays so support things like a flat network space.</p>

<p>The practical answer is no. There are no official guides and it's not officially supported.</p>
