OSPFv3 not announcing local IPv6 addresses

Hi,

I have a pretty straightforward OSPFv3 configuration with three (in future 4) routers - Configuration details see below.

However, whenever I add an IPv6 address to an interface (no mater if it is a "real" physical - like ehter 1, or a VLAN interface) the new subnet is not announced to the other routers.
Example:
Router 3 get the following address on his Test-VLAN Interface

add address=2001:470:747c:666::1 advertise=no interface=vlan666

The subnet-mask is 64

OSPFv3 route-list on Router 1 looks like this:

/routing ospf-v3> route print
 # DST-ADDRESS                                 STATE          COST      
 0 2001:470:1f0a:113::/64                      ext-1          10        
 1 2001:470:747c:10::/64                       intra-area     10        
 2 2001:470:747c:144::/64                      ext-1          10        
 3 2001:470:747c:220::/64                      ext-1          10        
 4 2001:470:747c:2201::/64                     intra-area     10        
 5 2003:0:0:5::/64                             imported-ext-1 20        
 6 fe80::/64                                   ext-1          10

OSPF with IPv4 works without any problems - firewalls are pretty much opened as they currently only reside in their own closed subnet.

I'm pretty unsure what could leads to this problem - maybe someone has a solution...

Area

Router1:

/routing ospf-v3 area-id=0.0.0.0 disabled=no instance=switch name=backbone type=default

Router 2:

/routing ospf-v3 area-id=0.0.0.0 disabled=no instance=backup name=main type=default

Router 3:

/routing ospf-v3 area-id=0.0.0.0 disabled=no instance=backup name=backbone type=default

Interfaces
Router 2 and Router 3 are only listening on VLAN Interfaces for Updates. Router 1 also has a OpenVPN Tunnel to an external server - which will be my IPv6 gateway to the internet - but that currently can be ignored.
