Dear all,
A quick note to remind you that as a layer-2 exchange, the MIXP in no way restricts what version of IP traffic flows across it.
It’s a switching fabric, and IPv6 works just as well as IPv4!
Of course, both peers need to already be supporting IPv6, but when that is the case there is no reason not to configure an IPv6 BGP session in parallel to IPv4 and exchange IPv6 traffic too.
Note that the IPv6 range for the peering LAN at the MIXP is: 2001:43f8:270:d0d0::/64
And the assignment of specific peering addresses simply matches the last hextet to last octet of the IPv4 address.
For example, if your IPv4 peering address is 196.223.0.1, then your IPv6 address is 2001:43f8:270:d0d0::1. Likewise, 196.223.0.15, becomes 2001:43f8:270:d0d0::15. And so on.
I am sure that there are members already peering with IPv4 that do both already run IPv6 on their own networks... If so, there is no reason not to peer with IPv6 also!
Just do it!
