DHCPv6 Overview

The IPv6 Dynamic Host Configuration Protocol (DHCPv6) provides services for delivering DHCPv6 server options to requesting clients. DHCPv6 options are contained in a DHCPv6 pool. The pool is assigned to the DHCPv6 server to which the client requests server options information.

Use the ipv6 dhcp pool command in global router configuration mode to create the DHCPv6 server pool and enter pool configuration mode.

Use the ipv6 dhcp server command in interface configuration mode to assign the pool to the DHCPv6 server. The assigned pool must already be created before you assign the pool to a DHCPv6 server.

Use this domain-name command to return one or more domain names when responding to a DHCPv6 client request.

Use the dns-server command to assign one or more DNS servers to DHCPv6 clients.

Use the nis-domain-name command to return one or more Network Information Services (NIS) domain names when responding to a DHCPv6 client request.

Use the nis-server command to assign one or more Network Information Services (NIS) servers to DHCPv6 clients.

Use the nisp-domain-name command to return one or more Network Information Services (NIS) version 2 domain names when responding to a DHCPv6 client request.

Use the nisp-server command to assign one or more Network Information Services (NIS) version 2 servers to DHCPv6 clients.

Use the sip-domain-name command to return one or more Session Initiation Protocol (SIP) domain names when responding to a DHCPv6 client request.

Use the sip-server command to assign one or more Session Initiation Protocol (SIP) servers to DHCPv6 clients.

Use the sntp-server command to assign a Simple Network Time Protocol (SNTP) server to DHCPv6 clients.

Use the unicast-server command to assign a unicast server to DHCPv6 clients.

Use the information-refresh command to configure the amount of time a client should wait before refreshing information from the DHCPv6 server.
