Multiple CIDRs network¶
In the Bootstrap Configuration it’s possible to provide several CIDRs for a single network, it’s needed when several nodes does not sit in the same network.
This kind of deployment needs good knowledge about networking, as each workload node needs to be able to communicate with all others, even those in a different workload CIDR.
In this case IP-in-IP encapsulation is likely needed.
Some explanation can be found about this subject in Calico documentation.
