•6rd Configuration Mode:
-Manual—Manually set 6rd Prefix, Relay IPv4 Address, and IPv4 Mask Length as provided by your ISP.
-Auto (DHCP)—Use DHCP (option 212) to obtain 6rd Prefix, Relay IPv4 Address, and IPv4 Mask Length.
•6rd Prefix—6rd Prefix for your ISP account.
•Relay IPv4 Address—Relay IPv4 address for your ISP account.
