You have two options
- To set up a DHCP relay agent (as stated by Ron Maupin
- To set a IPv6 pool in your Cisco router
DHCP relay agent
# config term
(config)# interface [interface-1]
(config-if)# ipv6 dhcp destination [destination ipv6 address] [interface-2]
Where interface-1 is the interface which will be set with the DHCPv6 address and interface-2 is the interface which will be acting as the relay.
Remember that, in order for this to work, the address set for your relaying interface has to be routable.
In order to see the information of the received address:
# show ipv6 dhcp interface
Stateful configuration by Cisco Routers
(config)# ipv6 unicast-routing
(config)# ipv6 dhcp pool [pool name]
(config)# addreess prefix [IPV6 \64] lifetime infinite inifinite
(config)# dns-server [ipv6 address of DNS Server]
(config)# domain-name [mydomain.org]
To assign an interface to the pool:
(config-if)# ipv6 dhcp server [pool name]
(conifg-if)# ipv6 enable [mode]-commit
Where mode may be either rapid or normal commit. An example of the prefix may be 2010:BB:BB:11::/64.
