 ### Is there support for multiple supernodes?
 
-As of now, one additional supernode is supported. The additional supernode is handled in a backup-fashion: A reserve-supernode can be started if one fails. The reserve-supernode just has to be known to the edges beforehand (simply by an additional `-l <ip:port>` at the edge).
-
-Actively using several supernodes in parallel will have the network fall apart (partitioned – some edges connected to one supernode, some to another).
-
-Considering these known limitations, current discussions however seem to include thoughts on increasing supernode reliability as well as fall-back mechanisms and might even shift more towards a full p2p-approach which then would not require a supernode at all, every node could be equal highly increasing network resilience.
+Yes, there is. Please [read](https://github.com/ntop/n2n/blob/dev/doc/Federation.md) about how several supernodes can form a Federation to increase network resilience.
 
 
 ### Can a supernode listen on multiple ports?

 If the edge prematurely has ended in a non-regular way, i.e. by killing it using `kill -9 ...` or `kill -SIGKILL ...`, it did not have a chance to un-register with the supernode which still counts the edge for online. A re-registration with the same MAC or IP address will be unsuccessful then. After two minutes or so the supernode will have forgotten. A new registration with the same parameters will be possible then. So, either wait two minutes or chose different parameters to restart with.
 
-And, as a matter of principal, always end an edge by either pressing `CTRL` + `C` or by sending SIGTERM or SIGINT by using `kill -SIGTERM ...` or `kill -SIGINT ...`! A plain `kill ...` without `-9` will do, too. And finally, a `stop` command to the management port peacefully ends the edge as well.
