Initial dualnet set up (without routing yet)
Changed initial positioning slighty so that network 2 is a chain with GW on one side of DC and nodes on the other (still without routing yet)
Dual network with 10 hosts and a dc each, both dc's also connected to the backend via a dual hop link.
Tested Neighbor Discovery parameter min/maxIntervalsBetweenRAs to suppress neighbor discovery for every UDP packet (without luck so far)
