Hi James, One more issue that maybe needs some consideration:How would a router know the boundary for dissemination of ULA prefixes? Here I am thinking of the case where there may be more than one ISP interface and particularly in the case of network splits and joins in the home. So really

Hi Douglas, As one who follows the WG and having a keen interest in homenet solutions, I fail to see how TRILL addresses the homenet problem set. Producing a flat L2 architecture and then trying to set up specific service filters to contain the traffic seems like an L3 problem to me. Claiming

Hi Tim, One more consideration: In the home, it is possible that multiple independent subnets could be combined, each with their own ULA prefix. This would happen in cases where the homeowner buys multiple silo'ed solutions (like a home automation system, Wi-Fi AP with connected MACs/Pcs, etc)

As one of the silent ones in Lee's note, I agree with what he is saying. While homenet needs to define a home routing solution, the following are the requirements for that solution from my perspective: 1) Must be an established, existing, deployed routing protocol (or heavily based on one). We

Hi Anders, +1 on what you wrote. Here is another reason that ULAs are needed: 1) If globals were used on the sub nets in your example, there would be a dependence on the ISP serving the prefix that is unwanted for communication within the home (eg, on/off for lighting within the home). 2) For
