Provision neutron-dynamic-routing

[Macks]

I would like to have tenants self-service IPv6 cidr to their subnets, similar to how AWS EC2 does it. My external router is x:x:x::1/64 on vlan 100, and I have set up a provider network on the same vlan and with cidr taken from the first /64 of subnet pool x:x:x::/48.

A tenant creates his subnet from this subnet pool, and a openstack router in my provider network. This will make the router have external ip x:x:x::a.b.c.d on vlan 100 and e.g. ip x:x:x:1::1/64 on vlan 101 (tenant's private network). To be usable, the openstack router needs to set static route ::/0 via x:x:x::1/64. Because this is not nat, my external router also needs to set route x:x:x:1::/64 via x:x:x::a.b.c.d.

My understanding is the only way to do this automatically with neutron is neutron-dynamic-routing. However, I'm not sure this is supported by openstack helm atm. Any help would be appreciated.
