DHCPv6 Commands

This command has no default configuration.

Interface Configuration (VLAN, Tunnel) mode

If 

relay-address is an IPv6 global address, then relay-interface is not required. 

If 

relay-address is a link-local or multicast address, then relay-interface is 

required. Finally, a value for 

relay-address is not specified, then a value for 

relay-interface must be specified and the DHCPV6-ALLAGENTS multicast 

address (i.e. FF02::1:2) is used to relay DHCPv6 messages to the relay server. 

An IP interface (VLAN) can be configured in DHCP relay mode or DHCP 

server mode. Configuring an interface in DHCP relay mode overwrites the 

DHCP server mode and vice-versa.
An IP interface configured in relay mode cannot be configured as a DHCP 

client (ip address dhcp).

The following example configures VLAN 15 for DHCPv6 relay functionality.

console(config)#interface vlan 15

console(config-if-vlan15)#ipv6 dhcp relay destination 2020:1::1

Use the ipv6 dhcp server command in Interface Configuration mode to 

configure DHCPv6 server functionality on an interface. For a particular 

interface DHCPv6 server and DHCPv6 relay functions are mutually exclusive.

ipv6 dhcp server 

pool-name [rapid-commit] [preference pref-value]

•

pool-name — The name of the DHCPv6 pool containing stateless and/or 

prefix delegation parameters

• rapid-commit — Is an option that allows for an abbreviated exchange 

between the client and server.
