NSX IPv6 Support

This week I got some good questions from a customer about NSX, especially on NSX IPv6 support.
 

NSX IPv6

And I knew which features are not supported:

  • Distributed logical router: The DLR does not support IPv6 forwarding / routing.
  • Dynamic routing (OSPF, BGP): Only IPv6 static routes are supported on the Edge Services Gateway.
  • NAT, SLAAC and DHCPv6 on NSX Edge: The workloads should use static IPv6 address allocation.
  • But I couldn’t immediately answer the question which components of NSX supported what connectivity like IPv4, IPv6 or dual stack. To make things worse the NSX 6.2 Documentation Center does not contain a lot of information about the IPv6 support… Luckily for me (and the customer) some insiders provided me the necessary information and I would like to share this with you.
