Chapter 6 Broadband IPv6 Rapid Deployment Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When the Device has an IPv4 WAN address and you set IPv6/IPv4 Mode to IPv4 Only, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISP's IPv4 network. The Device generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISP's Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local network can also use IPv4 services. The Device uses it's configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet. Figure 19 IPv6 Rapid Deployment LAN - IPv6 - IPv4 WAN - IPv4 - IPv6 in IPv4 IPv6 + IPv4 ISP (IPv4) IPv6 in IPv4 IPv4 IPv4 Internet BR IPv6 Internet Dual Stack Lite Use Dual Stack Lite when local network computers use IPv4 and the ISP has an IPv6 network. When the Device has an IPv6 WAN address and you set IPv6/IPv4 Mode to IPv6 Only, you can enable Dual Stack Lite to use IPv4 computers and services. The Device tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP's Address Family Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also use IPv6 services. The Device uses it's configured IPv6 WAN IP to route IPv6 traffic to the IPv6 Internet. VMG1312-B Series User's Guide 69

Use Dual Stack Lite when local network computers use IPv4 and the ISP has an IPv6 network.
When the Device has an IPv6 WAN address and you set
IPv6/IPv4 Mode
to
IPv6 Only
, you can
enable Dual Stack Lite to use IPv4 computers and services.
The Device tunnels IPv4 packets inside IPv6 encapsulation packets to the ISP’s Address Family
Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also
use IPv6 services. The Device uses it’s configured IPv6 WAN IP to route IPv6 traffic to the IPv6
