DESCRIPTION
Type the vendor string to be sent to the DHCP server.
An Identity Association (IA) is a collection of addresses assigned to the VMG, through which
the server and VMG can manage a set of related IP addresses. Each IA must be associated
with exactly one interface. The VMG uses the IA assigned to an interface to obtain
configuration from a DHCP server for that interface. Each IA consists of a unique IAID and
associated IP information.
Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for
identification when they are exchanging messages. The DUID is generated from the MAC
address, time, vendor assigned ID and/or the vendor's private enterprise number registered
with the IANA.
Use Option 125 (Vendor-Identifying Vendor-Specific) for TR-069 assignment (RFC 3925).
for more information.
This is available only when you select IPv6 Only in the IPv6/IPv4 Mode field. Select
Enable to let local computers use IPv4 through an ISP's IPv6 network.
Specify the transition router's IPv6 address.
This is available only when you select IPv4 Only in the IPv6/IPv4 Mode field. Select
Enable to tunnel IPv6 traffic from the local network through the ISP's IPv4 network.
Select Static if you have the IPv4 address of the relay server, otherwise select DHCP to
have the Device detect it automatically through DHCP.
Enter the subnet mask number (1~32) for the IPv4 network.
When you set the 6RD Type to Static, specify the relay server's IPv4 address in this field.
Enter an IPv6 prefix for tunneling IPv6 traffic to the ISP's border relay router and connecting
to the native IPv6 Internet.
Select Automatic if you want to have the VMG use the IPv6 prefix from the connected
router's Router Advertisement (RA) to generate an IPv6 address.
•
Select Get IPv6 Address From DHCPv6 Server(IA_NA) if you want to obtain an IPv6
address from a DHCPv6 server. The IP address assigned by a DHCPv6 server has priority
over the IP address automatically generated by the VMG using the IPv6 prefix from an
RA. This option is available only when you choose to get your IPv6 address
automatically.
•
Select Prefix Delegation(IA_PD) to use DHCP PD (Prefix Delegation) which enables
the Device to pass the IPv6 prefix information to its LAN hosts. The hosts can then use
the prefix to generate their IPv6 addresses.
Select Static if you have a fixed IPv6 address assigned by your ISP.
Select None to not assign any IPv6 address to this WAN connection.
Enter the address prefix length to specify how many most significant bits in an IPv6 address
compose the network address.
Enter the IP address of the next-hop gateway. The gateway is a router or switch on the
same segment as your VMG's interface(s). The gateway helps forward packets to their
destinations.
