NOTE:
You can configure up to eight DNS server addresses, one domain name, eight SIP server addresses, and
eight SIP server domain names in an address pool.
Enabling the DHCPv6 server on an interface
To enable the DHCPv6 server to assign IPv6 prefixes to clients, you must apply an address pool when
enabling the DHCP server on the interface. If you only need the DHCPv6 server to assign IPv6 addresses
to clients, you do not need to apply an address pool.
Configuration guidelines
Follow these guidelines when you enable the DHCPv6 server on an interface:
•
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.
•
Only one address pool can be applied to an interface.
•
A non-existing address pool can be applied to an interface, but the server cannot assign any prefix,
address, or other configuration information from the address pool until the address pool is created.
•
You cannot modify the address pool applied to an interface or parameters such as the server
priority by using the ipv6 dhcp server command. To do so, you must disable the DHCPv6 server on
the interface first.
