IP Tunnel
16.1 IPv6inIPv4 (6RD)
Use IPv6 Rapid Deployment (6RD) when the local network uses IPv6 and the ISP has an IPv4
network. When the GPON Device has an IPv4 WAN address and is configured to
IPv4 only
, you can
enable 6RD to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
The GPON 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 GPON Device uses it’s configured IPv4 WAN IP to route
IPv4 traffic to the IPv4 Internet.

Click
Advanced Setup > IP Tunnel > IPv6inIPv4
to view and configure IPv6 through IPv4
tunneling. This will encapsulate IPv6 packets in IPv4 packets so they can travel through IPv4
networks.
