I don't 'think' it's an MTU issue, even a simple IPv6 ping won't go across the P2P circuit.
On the CRS317, if I torch Vlan3000 on the ccr1009 interface, I see the IPv6 icmp packets coming in from my CCR1009, but if I torch the Interface going to the P2P circuit on the CRS317, I see no IPv6 traffic. Is that a problem, or because of the way the Mikrotik packet flows work, I would only see traffic as it enters the router, and since there is no reply from the far end, nothing would show up.

I don't think MTU would be the issue. If the endpoint has a 1500 byte MTU then it will send IP packets up to 1500 bytes long. IPv6 header is a little longer, but that means the data portion will just have to be a little shorter. So if you had an MTU issue with v6 you'd have an MTU issue with v4 also.

The ip6 traffic is encapsulated in the vlan? Ip6 headers I'm assuming are larger because the number itself is longer, mtu. But I'm just now learning to use vlans and I lick the tasty windows so I dont know a lot

Unless you've defined it as a protocol based VLAN then no it shouldn't
matter.
