IP addresses of the CM management system:

Procedure
Step 1
Configure the IP address of the VLAN Layer 3 interface.
huawei(config)#
ipv6
//Enable IPv6 packet forwarding.
huawei(config)#
vlan 100
huawei(config)#
interface vlanif 100
huawei(config-if-vlanif100)#
ipv6 enable
//Enable IPv6 on ports.
huawei(config-if-vlanif100)#
undo ipv6 nd ra halt
//enables a router to send
RA messages.
huawei(config-if-vlanif100)#
ipv6 nd autoconfig managed-address-flag
//Configure
the state-based auto-configuration address flag bit. The host obtains an IPv6
address using the state-based automatic configuration.
huawei(config-if-vlanif100)#
ipv6 address 2001:0db8:0001::1/64
//Configure the
IP address of the gateway for the DHCP domain of CMs.
huawei(config-if-vlanif100)#
ipv6 address 2001:0db8:0003::3/64
//Configure the
IP address of the gateway for the DHCP domain of PCs with fees paid.
huawei(config-if-vlanif100)#
ipv6 address 2001:0db8:0004::4/64
//Configure the
IP address of the gateway for the DHCP domain of overdue PCs.
huawei(config-if-vlanif100)#
quit
Step 2
Enable duplicate address detect (DAD) proxy, which prevents repeated link local addresses
(LLAs) on the user side.
After receiving a DAD packet sent from the user side with destination IP address LLA, the OLT
with DAD proxy enabled checks user online information based on the destination IP address
and VLAN. If a user with the same IP address in the VLAN has been online, the OLT makes a
response and prohibits the new user from going online. Otherwise, the OLT does not make a
response.
huawei(config)#
ipv6 dad proxy enable
huawei(config)#
vlan service-profile profile-id 10
huawei(config)#
vlan bind service-profile 100 profile-id 10
huawei(config-vlan-srvprof-10)#
ipv6 dad proxy enable
//DAD proxy takes effect
after it is enabled at system level and VLAN service profile level.
Step 3
Configure the working mode of DHCP relay to Layer 3 Option 16.
Option 16 is an option with code 16 in DHCPv6 packets, which identifies terminal types. In
DHCPv6 Option 16 mode, packets select a DHCPv6 server based on the Option 16 domain.
Therefore, in DHCPv6 Option 16 mode, packets select a DHCPv6 server based on terminal
types.
huawei(config)#
dhcpv6 mode layer-3 option16
Several minutes may be required and no action can be taken during this period
Are you sure to perform this operation? (y/n)[n]:

Step 4
Configure the IP addresses of the servers in a DHCP server group.
huawei(config)#
dhcpv6-server 0 ipv6 2001:0db8:0006::8/64 2001:0db8:0006::9/64
//
Configure DHCP server group 0 to allocate IP addresses for CMs.
