IPv6 on 5800 - Getting more than one IP with stateless

[JonisFEARP]

Hi!

I'm trying to implement IPv6 here, but i'm getting some problems. I have 3 interface vlan's and I'm trying to allocate one /64 block for each VLAN with Stateless enabled in router. The problem is that my clients are getting IP (v6) from all VLAN's, not the only one.

ex:

Client VLAN = 227
Get IPv4 for VLAN 227  using our DHCP, ok.
Get 3 IPv6 for VLAN 227, 209 and 230, all using Stateless configuration.

What I'm doing wrong? This is my interface vlan configuration (each one has identical configuration, changing only IP and IP block)
