IPv4 and IPv6 Dual Stack in a DHCP Access Network
Figure 1 shows a dual-stack interface stack in a DHCP access network. The IPv4 family (inet) and the IPv6 family (inet6) can reside on the same VLAN interface.
Figure 1: Dual-Stack Interface Stack over a DHCP Access Network

![]() | Note: When you are using IPv4 and IPv6 dual stack on the same DHCP interface, you must configure one dynamic profile for both the IPv4 and IPv6 subscribers. You cannot run IPv4 and IPv6 subscriber sessions over the same interface if you configure separate dynamic profiles for IPv4 and IPv6. |
Support for Demultiplexing Interfaces
IPv4 and IPv6 dual stack is supported on VLAN demultiplexing (demux) interfaces. Dual stack is not supported on IP demux interfaces.
