Ability to route IPv6 !=3D ability to route IPv6 as well as IPv4. =
Depending on the hardware, there will always be unavoidable tradeoffs, =
which tend to be either in reduced throughput capacity, typically =
noticed on particularly on software-switching platforms, or the number =
of routes/ACLs/etc you can put in the CAM of a hardware-switching box.
Most hardware sold today has plenty of headroom to do both, but don't =
forget that flinging v6 packets around is inherently more =
resource-intensive than flinging v4.=20
