6. Route-Views IPv6: July This instability of 8 routes in the week following the 6Bone phaseout was not a localized routing issue. It appears that the route instability related to an inconsistent configuration between two IPv6 transit providers. It also appears to be unrelated to the 6bone phaseout

8. V6 BGP Update Rates – June 06 This was an instability in the transit configuration of 2 IPv6 transit networks, and not related to the 6Bone phaseout

11. Observations The 6Bone phaseout occurred between the 6 th and the 29 th June 2006 without any visible effects on the operational stability of IPv6 V6 connectivity appeared to have been phased over well in advance of the 6/6/06 date The week of the 9 th – 14 th June saw ~8 non- 6Bone prefixes generate some levels of route instability. This was related to a AS30071 TBone / AS109 route oscillation for these non-6Bone address prefixes, and was not directly related to the 6Bone phaseout

12. 6Bone Cleanup There were no operational instabilities that could be attributed to the phaseout of the 6Bone networks The IANA IPV6 global Unicast Address Assignment has been updated to reflect the termination of the 6Bone experiment L 4 x 6Bone prefixes remain in the IPv6 routing table
