Assuming the IPv6 traffic is traversing the same physical ports as IPv4
between both networks, it is actually unnecessary pain to not pass IPv6
traffic across their interconnect relationship, unless removal of IPv6
peering lowers traffic utilization significantly to negate the need for
Google to pay a higher rate to Cogent, and/or delay physical port speed
upgrades.
