Can you elaborate the scenario where a subnet-id renumbering would be desireable, and would we want to actually signal this situation explicitely? -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | network architect [ ] m...@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
