CLI Reference Guide
Unspecified, loopback and node-local multicast addresses are not acceptable as
the relay destination. If any one of them is configured, the message "Invalid
destination address" is displayed.
Note that it is not necessary to enable the relay function on an interface for it to
accept and forward an incoming relay reply message from servers. By default,
the relay function is disabled, and there is no relay destination on an interface.
The no form of the command removes a relay destination on an interface or
deletes an output interface for a destination. If all relay destinations are removed,
the relay service is disabled on the interface.
DHCP for the IPv6 client, server, and relay functions is mutually exclusive on an
interface. When one of these functions is already enabled and a user tries to
configure a different function on the same interface, one of the following
messages is displayed: "Interface is in DHCP client mode," "Interface is in DHCP
server mode," or "Interface is in DHCP relay mode."
One VLAN interface only can be configured to one DHCP relay server.
This example shows how to sets the relay destination server address on vlan1:
