DHCPv6 server configuration examples
Example: Configuring dynamic IPv6 prefix assignment
Network configuration
As shown in
, the router acts as a DHCPv6 server to assign an IPv6 prefix, a DNS server
address, a domain name, a SIP server address, and a SIP server name to each DHCPv6 client.
The router assigns prefix 2001:0410:0201::/48 to the client whose DUID is
00030001CA0006A40000, and assigns prefixes in the range of 2001:0410::/48 to
2001:0410:FFFF::/48 (excluding 2001:0410:0201::/48) to other clients. The DNS server address is
2::2:3. The DHCPv6 clients reside in the domain
aaa.com
. The SIP server address is 2:2::4, and the
SIP server name is
bbb.com
.
