Command Reference Guide
ipv6 dhcp relay destination <ipv6 address>
Use the ipv6 dhcp relay destination command to enable Dynamic Host Control Protocol (DHCP) for
Internet Protocol version 6 (IPv6) and to specify the IPv6 address for the DHCPv6 messages. Using the no
form of this command disables the relay functionality for the specified destination. When all destinations
are removed, DHCPv6 relay functionality is disabled on the interface. Variations of this command include:
ipv6 dhcp relay destination <ipv6 address>
ipv6 dhcp relay destination <ipv6 address> <interface>
Syntax Description
<ipv6 address>
<interface>
Default Values
By default, no DHCP relay agent destinations are configured and the relay agent mode is disabled.
Command History
Release 18.2
Release R10.1.0
Functional Notes
To configure an interface to function as a DHCPv6 relay agent, you must first enable IPv6 on the interface
using the command ipv6.
Usage Examples
The following example enables DHCPv6 relay agent functionality and specifies the destination address as
2001:DB8:2::1:
(config)#interface loopback 1
(config-loop 1)#ipv6
(config-loop 1)#ipv6 dhcp relay destination 2001:DB8:2::1
60000CRG0-35E
Specifies the IPv6 address for the DHCPv6 messages. IPv6 addresses
should be specified in colon hexadecimal format (X:X:X:X::X). For
example, 2001:DB8:1::1.
Optional. Specifies an output interface to use when sending messages to
the DHCPv6 server. If no interface is specified, the interface is selected by
the routing table. This parameter is only required when the IPv6 address is
a link-scoped address. Interfaces are specified in the <interface type>
<slot/port | interface id> format. For example, for an Ethernet interface, use
eth 0/1. Type ipv6 dhcp relay destination <ipv6 address> ? to display a
list of valid interfaces.
Command was introduced.
Command was expanded to include the tunnel interface.
