comment Routing Issue - can't ping gateway from other routers in full mesh
RouterOS has a CLI. The command "/ip route print" is your friend. Make sure the destination you are trying to reach has a route back toward the source via the interface you expect. The source IP should be the outgoing interface's IP address unless otherwise specified.

How do you expect to reach the IPv6 internet?

It sounds like you are describing a NAT scenario. Don't do this.

comment static ipv6 route into a lxc container
I suggest you try the NDP proxy method before you label it unhelpful. In addition, I am not sure you understand the difference between having a /64 assigned to your provider-facing interface vs. having the provider route a /64 or larger to your host. You can do your testing on a DigitalOcean VM or Linode VM. Linode will route a /64 to your host upon email request. You can test the scenario with only a /64 on your provider-facing interface using either IaaS provider.

comment How do I disable the metadata lookup at cirros boot?
I understand how some might view this as a development/test question. Let me provide an example of a production use case. Using cirros as a "pinger VM" to measure VM to VM, host to host, or rack to rack latency/jitter/packet delivery. If these VMs are spun up dynamically to obtain a measurement ASAP, you wouldn't need the metadata service and you probably wouldn't want to set-up an HTTP server to send metadata. The VM's boot time is vital and any optimizations are helpful.

I suspect the two end systems are not identical or the networking configuration at your sites differs. You might want to try the test again and avoid as much middleware as you can. Plug directly into the WAN routers at the sites. A provider issue is possible but unlikely.

It would be helpful if you could include a diagram and a description of what you are looking to achieve in terms of redundancy.

comment Ubuntu 14.04 dropping ipv6 route and ifstate
Router advertisement. It's a fundamental component of neighbor discovery (roughly the IPv6 equivalent of ARP but with more functionality).
