Hi all,

I am trying to figure out how to enable workloads on overlay to use IPv6
addresses and communicate with external networks.
I have to use Neutron ML2/OVN in my scenario and I have doubts regarding
how the external networks(Internet) can know how to reach the VMs using
IPv6 address behind a regular neutron router.
I was checking this link
that uses the BGP speaker on neutron in order to advertise the /64 subnets
to a border router, that option should work fine but Neutron/BGP Speaker is
not supported with OVN as I could check on the documentation.
How are you using IPv6 integration (Neutron/OVN) to advertise the /64
