Step 3
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 4
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]:
y
Step 5
Enable DHCPv6 Option.
No authentication and security mechanisms are available for DHCPv6. Therefore, the
application of DHCPv6 faces multiple security issues on networks. The enabled DHCPv6 Option
function resolves these issues.
huawei(config)#
dhcpv6 option enable
Step 6
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.
huawei(config)#
dhcpv6-server 1 ipv6 2001:0db8:0006::10/64
2001:0db8:0006::11/64
//Configure DHCP server group 1 to allocate IP addresses
for PCs.
Step 7
Create DHCP Option 16 domains.
huawei(config)#
dhcp domain default
//Create Option 16 domain
default
for PCs.
huawei(config-dhcp-domain-default)#
dhcpv6-gateway learning enable
//PCs require
different IP address segments based on fee payment state. Therefore, automatic
gateway learning must be enabled on the OLT.
huawei(config-dhcp-domain-default)#
dhcpv6-server 1 vlan 100
/Bind DHCP
server group 1 to the DHCP domain of PCs. After the configuration, the PCs in this
DHCP domain are mapped to DHCP server group 1.
huawei(config-dhcp-domain-default)#
quit
huawei(config)#
dhcp domain docsis
//Create Option 16 domain
docsis
for CMs.
huawei(config-dhcp-domain-docsis)#
dhcpv6-server 0 vlan 100
//Bind DHCP server
group 0 to the DHCP domain of CMs. After the configuration, the CMs in this DHCP
domain are mapped to DHCP server group 0.
huawei(config-dhcp-domain-docsis)#
quit
Step 8
Configure the IP addresses of the gateways for DHCP domains.
huawei(config)#
interface vlanif 100
huawei(config-if-vlanif100)#
dhcp domain default gateway ipv6 2001:0db8:0003::3/64
2001:0db8:0004::4/64
//Configure IP addresses of the gateways for the DHCP
domain of PCs, including the IP address of the gateway for the PCs with fees paid
and the IP address of the gateway for overdue PCs.
huawei(config-if-vlanif100)#
dhcp domain docsis gateway ipv6
2001:0db8:0001::1/64
//Configure the IP address of the gateway for the DHCP
