Chapter 6 Broadband Table 11 Network Setting > Broadband > Add New WAN Interface/Edit (Routing Mode) (continued) LABEL DESCRIPTION Tunnel The DS-Lite (Dual Stack Lite) fields display when you set the IPv4/IPv6 Mode field to IPv6 Only. Enable Dual Stack Lite to let local computers use IPv4 through an ISP's IPv6 network. See Dual Stack Lite on page 71 for more information. Enable DS-Lite This is available only when you select IPv6 Only in the IPv4/IPv6 Mode field. Select Enable to let local computers use IPv4 through an ISP's IPv6 network. DS-Lite Relay Server IP Specify the transition router's IPv6 address. 6RD The 6RD (IPv6 rapid deployment) fields display when you set the IPv6/IPv4 Mode field to IPv4 Only. See IPv6 Rapid Deployment on page 70 for more information. 6RD Select Enable to tunnel IPv6 traffic from the local network through the ISP's IPv4 network. Select Manually Configured if you have the IPv4 address of the relay server. Otherwise, select Automatically configured by DHCPC to have the VMG detect it automatically through DHCP. The Automatically configured by DHCPC option is configurable only when you set the method of encapsulation to IPoE. Service Provider Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP's border relay router and connecting to the IPv6 Prefix native IPv6 Internet. IPv4 Mask Length Enter the subnet mask number (1~32) for the IPv4 network. Border Relay IPv4 Address When you select Manually Configured, specify the relay server's IPv4 address in this field. DHCPC Options (This is available only when you select IPv4 Only or IPv4 IPv6 DualStack in the IPv4/IPv6 Mode field.) Request Options Select Option 43 to have the VMG automatically add vendor specific information in the DHCP packets to request the vendor specific options from the DHCP server. Select Option 121 to have the VMG push static routes to clients. Sent Options option 60 Select this and enter the device identity you want the VMG to add in the DHCP discovery packets that go to the DHCP server. Vendor ID Enter the Vendor Class Identifier, such as the type of the hardware or firmware. option 61 Select this and enter any string that identifies the device. IAID Enter the Identity Association Identifier (IAID) of the device, for example, the WAN connection index number. DUID Enter the hardware type, a time value and the MAC address of the device. option 125 Select this to have the VMG automatically generate and add vendor specific parameters in the DHCP discovery packets that go to the DHCP server. IPv6 Address (This is available only when you select IPv4 IPv6 DualStack or IPv6 Only in the IPv4/IPv6 Mode field.) Obtain an IPv6 Address Automatically Select Obtain an IPv6 Address Automatically if you want to have the VMG use the IPv6 prefix from the connected router's Router Advertisement (RA) to generate an IPv6 address. Static IPv6 Address Select Static IPv6 Address if you have a fixed IPv6 address assigned by your ISP. When you select this, the following fields appear. IPv6 Address Enter an IPv6 IP address that your ISP gave to you for this WAN interface. Prefix Length Enter the address prefix length to specify how many most significant bits in an IPv6 address compose the network address. VMG4927-B50A / VMG9827-B50A User's Guide 77
