Configuring the DHCPv6 server on an interface
Enable the DHCP server and configure one of the following address/prefix assignment methods on an
interface:
•
Apply an address pool on the interface
—The DHCPv6 server selects an IPv6 address/prefix from
the applied address pool for a requesting client. If there is no assignable IPv6 address/prefix in the
address pool, the DHCPv6 server cannot to assign an IPv6 address/prefix to a client.
•
Configure global address assignment on the interface
—The DHCPv6 server selects an IPv6
address/prefix in the global DHCPv6 address pool that matches the server interface address or the
DHCPv6 relay agent address for a requesting client.
If you configure both methods on an interface, the DHCPv6 server uses the specified address pool for
address assignment without performing global address assignment.
Configuration guidelines
•
An interface cannot serve as a DHCPv6 server and DHCPv6 relay agent at the same time.
•
Do not enable DHCPv6 server and DHCPv6 client on the same interface.
•
If you use the
ipv6 dhcp server
command multiple times, the most recent configuration takes effect.
•
You can apply an address pool that has not been created to an interface. The setting takes effect
after the address pool is created.
•
Only one address pool can be applied to an interface. If you use the
ipv6 dhcp server apply pool
command multiple times, the most recent configuration takes effect.
