Subject IPv6 plan - questions
Date Wed, 06 Mar 2013 09:36:46 GMT

I've been catching up on IPv6 plans by reading the functional specs
and Jira tickets - it's great to have so much material to refer to.

I still have a few questions though, and I'm hoping someone involved
with the feature can enlighten me.

*[Support for Providers other than Virtual Router]*
In [3], the spec says "No external device support in plan."
What does this mean exactly?

For example, if using Providers other than the Virtual Router, does
the UI still allow setting IPv6 addresses?

If so, do we attempt to pass IPv6 addresses to the Providers no
matter what, or do we check whether the Provider has IPv6 support?

*[Networking Modes]*
Advanced Shared mode and Basic mode are mentioned in the Jira
ticket [1] - "Isolated Network" is mentioned briefly in [2], but I
wanted to check if the Advanced Isolated and VPC modes are on the

*[IP Address Management / IPAM]*
>From [1], re: handing out IPv6 addresses: "One way could be that the
network admin creates a static route for a /48 towards a Virtual
Router and then the VR can hand out /64s to Instances."

With IPv4, IPAM is handled by the CloudStack management server, and
the VR is told which IP address to give to the VM over DHCP. Would
this change with IPv6? "The VR can hand out /64s to instances" sounds
like the VR is handling IPAM to some extent.

>From [3], "Router advertisement should be sent by public gateway in
the network." - to double-check, does this mean the router outside the
CloudStack network should send RAs, but the VR won't send RAs?
