DHCPv6 Commands
78-21075-01 Command Line Interface Reference Guide
Syntax
ipv6 dhcp relay destination [
no ipv6 dhcp relay destination [
Parameters
•
ipv6-address—Relay destination address. The following types of relay
destination addresses exist:
-
Link-local unicast. A user must specify an output interface for this kind of
address.
-
Global unicast IPv6 address. An output interface cannot be specified for
this kind of address.
This argument must be in the form documented in RFC 4291 where the
address is specified in hexadecimal using 16-bit values between colons.
If the argument is not configured then the well-known link-local Multicast
address All_DHCP_Relay_Agents_and_Servers (FF02::1:2) is defined.
•
interface-id—Specifies the output interface for a destination. If this
argument is configured, client messages are forwarded to the destination
address through the link to which the output interface is connected.
Default Configuration
The relay function is disabled, and there is no relay destination on an interface.
Command Mode
Interface configuration (config-if)
User Guidelines
This command specifies a destination address to which client messages are
forwarded, and it enables DHCP for IPv6 relay service on the interface.
DHCPv6 Relay inserts the Interface-id option if an IPv6 global address is not
defined on the interface on which the relay is running. The Interface-id field of the
option is the interface name (a value of the ifName field of the ifTable) on which the
relay is running.
When relay service is running on an interface, a DHCP for IPv6 message received
on that interface will be forwarded to all configured relay destinations configured
per the interface and globally.
