DHCP Relay
– 873 –
(i.e., this switch). This switch then broadcasts the DHCPv6 response received
from the server to the client.
â—† When the multicast option is used, the switch multicasts the modified client
request to all configured VLANs or to a specified VLAN, and enables DHCPv6
relay service for those VLANs.
â—† Up to five relay destinations may be configured by repeating this command.
â—† When issuing the no ipv6 dhcp relay destination command without any
arguments, the switch will delete all configured destination addresses and
disable DHCP for IPv6 relay for all VLANs.
EXAMPLE
Console(config)#interface vlan 1
Console(config-if)#ipv6 dhcp relay destination 2001:0DB8:3000:3000::42
