Configure a DHCPv6 Server to Statically Allocate IPv6 Addresses

Network Requirements

Device2 acts as a DHCPv6 server to allocate IPv6 addresses and DNS server IPv6 addresses in a static manner.
The DHCPv6 server allocates an IP address to PC1 in DUID binding mode, and allocates an IPv6 address to PC2 in the DUID+IAID binding mode.

Configuring a DHCPv6 Server to Statically Allocate IPv6 Addresses

Figure 6-1 Configuring a DHCPv6 Server to Statically Allocate IPv6 Addresses

Configuration Steps

Step 1: Configure the IPv6 address of the Device2 interface and the DHCPv6 server.

Device2#configure terminal
Device2(config)#interface vlan2
Device2(config-if-vlan2)#ipv6 address 1::3/64
Device2(config-if-vlan2)#ipv6 dhcp server
Device2(config-if-vlan2)#exit

Step 2: Configure the static binding address pool and parameters.

#Configure the address pool binding, and adopt the DUID binding mode to distribute IPv6 address for PC1. Adopt the static DUID+IAID binding mode to distribute the IPv6 address for PC2.

Device2(config)#ipv6 dhcp pool binding
Device2(dhcp6-config)#bind 1::11 duid 000200001613303030313761636635646634
Device2(dhcp6-config)#bind 1::12 duid 000200001613636364383166313037616239 iaid 00010071
Device2(dhcp6-config)#dns-server 1::2
Device2(dhcp6-config)#exit

Step 3:Check the result.

#Check the association of the server interface and address.

Device2#show ipv6 dhcp server interface vlan2
DHCPv6 server status information: 
DHCP server is enabled on interface: vlan2
Vrf : global 
 
DHCPv6 server pool information:
Available directly-connected pool: 
  Interface IP: 1::1/64 
      Pool name: binding 
      Range: 
             min: 101:: 
             max: 101::ffff:ffff:ffff:ffff 
        utilization: 0.00%

#Check the static binding of the server.

Device2#show ipv6 dhcp pool binding binding 
IPv6 Address                     Duid                   Iaid        Type      Time Left(s)
-------------   --------------------------------------  ----------  --------  ------------
1::11           000200001613303030313761636635646634    00000000    Binding   NA 
1::12           000200001613636364383166313037616239    00010071    Binding   NA

#On Device2, query the IPv6 addresses distributed for PC1 and PC2 via the show ipv6 dhcp pool binding lease command.

Device2#show ipv6 dhcp pool mac-binding lease  
IPv6 Address                   Duid                       Iaid        Type        Time Left(s) 
-------------    ------------------------------------     ---------   -------     ------------
1::11            000200001613303030313761636635646634     00000000    Lease       2591974 
1::12            000200001613636364383166313037616239     00010071    Lease       2591974

On PC1 and PC2, check whether the got IPv6 addresses, and the IPv6 address of the DNS server are correct.
