Hi,
I have a design question to my IPv6 lab.
I have multiple VLANs in my environment (see this picture).

VLAN 100 = Server
VLAN 200 = DMZ
VLAN 300 = Clients
VLAN 400 = WLAN
VLAN 600 = IPv6 Internet
VLAN 700 = IPv4 Internet
if VLAN 100 has the IPv4 192.168.1.0/24 would than the IPv6 for it be 2001:470:1b0a:7a1:1111::/64
and VLAN 300 has the IPv4 192.168.3.0/24 would than the IPv6 be 2001:470:1b0a:7a1:3333::/64
and VLAN 600 has the IPv4 192.168.6.0/24 would than the IPv6 be = 2001:470:1b0a:7a1:6666::/64

?
I got this prefix from tunnelbroker 2001:470:1b0a:7a1::/64
How do I separate this correctly for my VLANS?
Can anyone please give me please an example how to subnet this for 3 VLANs for example.
Or what is the best practice for this?
A other question is:
I get every 24 hours a new IPv4 address from my provider.
Will the tunnel automatically re-established after I got a new ipv4 address from my provider ??
My Config on the Cisco Router lookes like this:
#show running-config interface tunnel0
Building configuration...
Current configuration : 226 bytes
!
