Router OS. Just because I know it better. In theory with the Hardware
offloading, it should be the same, right?

Are you running router OS or switch OS on the switch?

It's a production switch, so I'll have to change it around during
a maintenance window. The switch is passing several vlans between
different ports, but this is the first IPv6 traffic I'm putting
through it.

The P2P provider is saying that they find no technical reason

I've plugged a couple more routers into the CRS317 to test
with. What I found is that if I have the PVID set to the Vlan,
and Admit all packets on the interface, then I can ping with
IPv6 between the 2 routers. But if I define a VLan on either
router, no IPv6 traffic passes.
Router1 <- Ethernet Cable -> Router2 Ipv6 works
Router1 <-CRS317 port1 PVID=3000 <-> CRS317 Port2 PVID=3000 ->
Router2 IPv6 works
Router1 <-CRS317 Port1 PVID=3000 <-> CRS317 Port2 -> Vlan3000
Router 2 IPv6 fails.
But even if I have the PVID of my P2P port and Router1 set the
same, I still can't ping an IPv6 address on the other end of the
P2P circuit. I'm about ready to give up and Kill my Dualstack.
Has anyone tried IPv6 with Vlans on a CRS317? Am I missing
something simple?

After escalating with the provider, they think that might be
what is happening. If what they're telling me is true, Their
Core network is running MPLS, but it's in a QinQ to the NID
that I'm plugged into. So all IPv4 is fine, but might not
pass IPv6.
So do I need to set anything special on my CRS317 bridge to
pass the IPv6 Traffic on the Vlans? The Only Ethertype setting
I see in the bridge interface itself, and you can only choose
0x8100, 0x88a8, or 0x9100

IPv4's Ethertype if 0x0800 whereas IPv6's Ethertype is
0x86dd. This field is right after the 802.1Q VLAN header in
the L2 header.

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
