Prefix Delegation
Prefix delegation enables an IPv6 router to use the IPv6 prefix (network address) received from the
ISP (or a connected uplink router) for its LAN. The Device uses the received IPv6 prefix (for
example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements
(RAs) regularly by multicast, the Device passes the IPv6 prefix information to LAN hosts. The hosts
use the prefix to generate their IPv6 addresses.
5.1.3 Before You Begin
You need to know your Internet access settings such as encapsulation and WAN IP address. Get this
information from your ISP.
5.2 The Broadband Screen
The Device must have a WAN interface to allow users to use the Ethernet WAN port or DSL port to
access the Internet. Use the Broadband screen to view or modify a WAN interface.
Click Network Setting > Broadband. The following screen opens.
