IPv6 Connection Types

IPv6 connection types

Important - The device can have only a single IPv6 Internet connection.

Static IPv6 - A fixed (non-dynamic) IP address.
Obtain automatically (DHCPv6/SLAAC) - In both Dynamic Host Configuration Protocol (DHCP) and Stateless Address Auto Configuration (SLAAC) the user does not set the IP as this is handled by the router/DHCP server. DHCPv6 issues a full IP address. SLAAC issues an IP address prefix, and the gateway completes the rest of the address according to discovery protocols.
PPPoE (IPv6 only) - A network protocol to encapsulate Point-to-Point Protocol (PPP) frames inside Ethernet frames. It is used mainly with DSL services where individual users connect to the DSL modem over Ethernet and Metro Ethernet networks.
PPPoE (IPv4/IPv6) - Same as PPPoE ( IPv6 only), but the user must first configure a type IPv4 PPPoE internet connection on the same interface. Use this option when the ISP provides both IPv4 and IPv6 addresses through the same PPPoE connection. This prevents the need to define the same dialer connection details more than once.
IPv6 Bridge - A Layer 2 bridge between internal and external networks, containing both IPv4 and IPv6 addresses (or just IPv6) to make the gateway reachable through the bridge in a dual stack/pure IPv6 network.
