Maybe not intentionally, but I think that will be the result. A usage case that has been shown has been a hospital whose network (with thousands of hosts) is a single broadcast domain. I think everyone can agree that instead of making such large broadcast domains, the network should be split up by routing instead. While TRILL would "fix" the usage case above so that using a single broadcast domain would still "work", that would still be very bad network design, and in the longer term, it would probably be counter-productive. (In our environment, what we've seen recently is *decrease* in the size of broadcast domains/subnets due to the requirements to isolate and filter the traffic from other hosts at the site. Using a single domain makes this security issue much worse.) -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
