[radvd-devel-l] Advertise different router?

[Dyonisius Visser]

Hi guys

I am in the process of setting up an IPv6 only network.
I have a dedicated VLAN for this, and assigned a /64 to it.
Our Cisco 3750 sends RAs on this network.

I have set-up a VM with Ecdysis to do nat64, and installed bind-9.8.0 to
do dns64. Installed dibbler as well on this VM to do DHCPv6.

So far it seems to work great, Windows 7 and iOS can connect and
everything (except Skype) works fine.

Now it would also like to have RFC5006 RDNSS being announced in the RAs.
Unfortunately our Cisco does not support that.

So my idea was to run radvd on the VM, so that does the RAs, and stop
doing it on the Cisco.

However radvd advertises the prefix but with itself as the router. This
works, but now all traffic is going through the VM, which is not what I
want, since we Cisco has native IPv6.

Maybe I'm asking a totally stupid question, but is it possible for radvd
to advertise a prefix with a different router? In my case I would like
radvd to announce the prefix with the Cisco as the router.

If this can work, I would 'only' have to run two autoconfiguration systems.

Thanks!!!
