so I figured out how to obtain a ipv6 prefix from my ISP (Timewarner) on my WAN router WAN interface.
interface GigabitEthernet8 description WAN ...
ipv6 address dhcp ipv6 enable ipv6 nd autoconfig default-route ipv6 tcp adjust-mss 1360 ipv6 dhcp client pd hint ::/56 ipv6 dhcp client pd twc-prefix ipv6 virtual-reassembly in
I also know how to use then networks out of the prefix on the WAN routers inside LAN interface.
interface Vlan1 description LAN Core VLAN ip address 192.168.1.1 255.255.255.0 ipv6 address twc-prefix 0:0:0:1::/64 eui-64 ipv6 enable ipv6 nd other-config-flag ipv6 tcp adjust-mss 1360 ipv6 dhcp server poolv6 ipv6 virtual-reassembly in
Now - beside just a WAN router (897VAW) I have also a LAN L3 switch (3850).
The users sit on VLANs on the LAN core switch - not L3 adjacent to the WAN router.
Is there a way to configure also a dhcp6 prefix pool on the WAN router which is a subset of the dynamic received tw-prefix pool?
Like I could specify a /58 out the /56 pool and allow hints of /60?
Then I could configured the 3850 also to make a dhcp prefix request and use those networks on the user VLAN.
