Does anyone have any experiences or insights to share on how more (or less) efficient routing is with IPv6? Any specific thoughts with respect to how the following characteristics help or not with routing efficiency? - fixed header size - Extension header chain - flow labels in header - no intermediate fragmentation - no checksums
One thing to think about is routing efficiency. At this time, networks that employ MPLS-TE for IPv4, and run native IPv6, have challenges doing the same for IPv6, mostly because it's not possible to point IPv6 traffic into MPLS-TE tunnels built over an IPv4 control plane. If you are doing 6PE, this could be possible, but most vendors can't do the former. More native IPv6 control planes for MPLS (and by extension, MPLS-TE) will mean that IPv6 traffic will travel the same path as IPv4 traffic in MPLS-TE'd networks. When that will be remains to be seen. Until then, the most we can do for native IPv6 traffic is fiddle around with IGP metrics, to obtain some kind of reasonable TE. Mark.
