Is it possible to configure the radvd config so that the router advertisement
packets got a VLAN- tag? Theres a switch between my Router (software router, Ubuntu OS) and I
only want some VLANs to recieve router advertisements. My switch isn't that powerful to
filter icmpv6 type 134 packets.

First you have to configure the VLANs on the Ubuntu box. This is documented in the VLAN page of the Ubuntu Wiki. First you have to make sure that the VLAN module is loaded into the kernel:
echo "8021q" | sudo tee -a /etc/modules
And then you create interfaces for the VLANs. In this example an interface is created for VLAN 10z on
eth1and it gets IPv6 address
2001:db8:ab:cd::1/64`:
auto eth1.10
iface eth1.10 inet6 static
address 2001:db8:ab:cd::1
netmask 64
vlan-raw-device eth1
After you create this interface you can configure radvd
as usual. Here is an example based on the IPv6 page of the Ubuntu Wiki:
interface eth1.10
{
AdvSendAdvert on;
prefix 2001:db8:ab:cd::/64
{
AdvOnLink on;
AdvAutonomous on;
};
};
