Slight Clarification on v6 addressing... On Thu, 2013-04-11 at 15:38 -0400, Michael H.

That's "should" as in the kernel should already have assigned your link-local v6 addresses to your interfaces. You don't have to provide them and I didn't mean to imply you needed to add them. Generally, if I'm using static IPv6 addresses, I take that link local address and replace the "fe80::" with the network prefix I'm assigning and leave the lower bits the same. That way it has the same address as would be assigned by stateless autoconf generated from router advertisements from a router. On Linux routers, you would use either zebra from the quagga package or radvd to provide router advertisements out to your clients and you'll probably need to add that to get the end clients to self configure properly.
