I wouldn't necessarily say that a layer 2 mesh is more difficult to troubleshoot than a layer 3 mesh with tunnels on top to achieve layer 2 functionality is... :) L2 mesh networks can be quite scalable, especially when separating end user traffic by performing l3 routing over the l2 mesh or by usi

I can't think of a reason why anyone would deploy a layer 2 mesh with an Ethernet based medium (which wifi inherently is). Conventional wisdom in large scale sp architecture is to do anything of any size or complexity in layer 3. Layer 2 is really bad at scalability and really hard to tro

Yes a layer 2 mesh is protocol dependent, so you're stuck to IP traffic only. Also, when using a layer 3 mesh, roaming and convergence time can also increase (slowing things down) as when things move around, extra things have to happen... layer 3 stuff... OLSR tables updated, IPs updated, ARP entr

For those who were curious as to what I did on my "multiple gateway" question, I actually ended up installing pfsense today and playing around with it for several hours. Once I kick around the "lagg" (link aggregation) features a bit, I'll let you know how they all work. The GUI isn't quite as
