Just plug his DSL model into a LAN port on the "router", or confuse his 8-port switch with his 8-port home router. What we are saying is that, the IPv6 portion of the network SHOULD continue to work, even if the topology can never work for IPv4. We had a brief discussion (making it out-of-scope very quickly) about whether or not the loop detection that IPv6 would provide could be communicated (by a vendor, inside their box) to their IPv4 side, which would permit them to turn off the R3/R2 loop for IPv4, making things work. -- ] He who is tired of Weird Al is tired of life! | firewalls [ ] Michael Richardson, Sandelman Software Works, Ottawa, ON |net architect[ ] m...@sandelman.ottawa.on.ca http://www.sandelman.ottawa.on.ca/ |device driver[ Kyoto Plus: watch the video <http://www.youtube.com/watch?v=kzx1ycLXQSE> then sign the petition.
