Parameters
•
ipv6-address— Relay destination address. There are the following types of
relay destination address:
relay destination address:
-
Link-local unicast. A user must specify an output interface for this kind of
address.
address.
-
Global unicast IPv6 address. An output interface cannot be specified for
this kind of address.
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.
address is specified in hexadecimal using 16-bit values between colons.
If the argument is not configured then the well know the link-local multicast
address All_DHCP_Relay_Agents_and_Servers (FF02::1:2) is defined.
address All_DHCP_Relay_Agents_and_Servers (FF02::1:2) is defined.
•
interface-id— Interface identifier that 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. If this argument is omitted then the Routing table is used.

User Guidelines
The ipv6 dhcp relay destination command specifies a destination address to
which client messages are forwarded. The address is used by all DHCPv6 relay
running in the switch.
which client messages are forwarded. The address is used by all DHCPv6 relay
running in the switch.
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.

Multiple destinations can be configured on one interface, and multiple output
interfaces can be configured for one destination. When the relay agent relays
