Dynamic Routing & IPV6

[yyzkevin]

I have a dual stack network offering in routed mode, with dynamic routing. It announces the IPV4 and IPV6 prefixes as expected.

When I setup a dual-stack offering in nat mode with dynamic routing, I can see FRR running on the VR but there is no configuration loaded.

Is this the expected behaviour?

env: Cloudstack 4.20.1

In NAT mode the VR shouldn't announce any prefix, correct? Or do you meant that it would still need to announce IPv6?

[yyzkevin]

My expectation was it will announce the IPV6 prefix still. Currently it does not and would need to make manual static /64 route upstream which is not manageable.

I am aware it is mentioned that IPV6 within isolated networks is only supported by static routing, however I assumed this to be outdated documentation given that it was working smoothly with the Isolated VR in Routing mode.
