ahcpd is enabled in client mode by default in this test series. So either you need to have an ahcpd server or two on the mesh running, or to assign ips manually in /etc/config/network for gw11 and gw01.
See the differences between /etc/config/ahcpd prior to 3.10 for how to setup a server version of ahcpd
It's nice to know someone is playing with and actually dependent on the meshy stuff.
I can revert back to server mode if you like but I had a reason for switching to ahcpd client mode by default. 33 machines in the lab are clients, and accidentally ending up with a rogue ahcp server on that caused me serious headaches. Several times. I could, I guess, leave the static ips up....
