For IS-IS, highly recommend MT to avoid any nasties while turning up v6 in a dual-stack environment.
Also when doing MT on cisco, configure "no-adjacency-check" under the v6 address-family during the migrate else you will bounce your sessions. Cisco of course warn you against doing this but without it the change is bumpy.
From the cisco docs:
"Disabling the adjacency-check command can adversely affect your network configuration. Enter the no adjacency-check command only when you are running IPv4 IS-IS on all your routers and you want to add IPv6 IS-IS to your network but you need to maintain all your adjacencies during the transition. When the IPv6 IS-IS configuration is complete, remove the no adjacency-check command from the configuration." source: http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-is-is.html ------------------------------------------------ David Freedman Group Network Engineering Claranet Limited http://www.clara.net
