IPv6 BGP on SD-WAN capture - retransmissions

[MerkiWaters]

Is anyone seeing similar traffic patterns like below on SD-WAN packet captures on an MX68W?  

Are the private IPv6 addresses standard Meraki SD-WAN BGP?

I'm seeing retransmissions like this in captures at multiple sites.

Yes , i suppose everyone
