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 relays
running on the switch.
When a 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 interface and globally.
Multiple destinations can be configured on one interface, and multiple output
interfaces can be configured for one destination.
Unspecified, loopback, and Multicast addresses are not acceptable as the relay
destination.
Use the no form of the command with the
ipv6-address and interface-id
arguments to remove only the given globally-defined address with the given
output interface.
Use the no form of the command with the
ipv6-address argument to remove only
the given globally-defined address for all output interfaces.
The no form of the command without the arguments removes all the
globally-defined addresses.
Examples
Example 1. The following example sets the relay unicast link-local destination
address per VLAN 200:
switchxxxxxx(config)# ipv6 dhcp relay destination FE80::1:2 vlan 200
Example 2. The following example sets that client messages are forwarded to
VLAN 200:
switchxxxxxx(config)# ipv6 dhcp relay destination vlan 200
Example 3. The following example sets the unicast global relay destination
address:
switchxxxxxx(config)# ipv6 dhcp relay destination 3002::1:2
