IPv6 and router advertisement

[Miłosz Oller]

Hi

I have a problem with RA. 
My BIRD config: http://wklej.org/hash/81158faf8c6/
My network config:
Protocol radv dc1 on router 1 is "master", protocol radv dc2 on router
2 is "master". 
vlan 10 - 14
On each vlan interface, eg bond1.10, are assigned addresses (with
keepalived):
eg 2001:67c:2ad8::1/64 and 2001:67c:2ad8:1::1/64

Problem is on router 2 and protocol dc2. When I assign the address on
vlan interface, eg 2001:67c:16f8:2::1/64 dev bond1.10 on router 2,
hosts in this vlan recive addresses with this prefix. 

Host in vlan 10
3: eth0.10 at eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 
    inet6 2001:67c:16f8:3:c9dd:c2cb:611e:bcfd/64 scope global temporary
dynamic 
       valid_lft 86397sec preferred_lft 14397sec
    inet6 2001:67c:16f8:3:216:3eff:fe35:578b/64 scope global dynamic 
       valid_lft 86397sec preferred_lft 14397sec
    inet6 2001:67c:16f8:2:c9dd:c2cb:611e:bcfd/64 scope global temporary
dynamic 
       valid_lft 86397sec preferred_lft 14397sec
    inet6 2001:67c:16f8:2:216:3eff:fe35:578b/64 scope global dynamic

With protocol dc1 on router 1 is everything ok. Hosts don't recive any
addresses.
Why host recive address from router?
