ipv6 helper-address
Configures a DHCPv6 server address.
Syntax
ipv6 helper-address ipv6-address [vrf vrf-name]
Parameters
• vrf vrf-name — (Optional) Enter the keyword vrf and then the name of the VRF through which the
host address can be reached.
• ipv6–address — Specify the DHCPv6 server address in the A::B format.
Defaults Disabled
Command Mode INTERFACE
Usage Information Use this command on interfaces to which DHCPv6 clients connect, to forward the packets between IPv6 clients
and a DHCPv6 server. After you configure an IPv6 helper address, the address forwards UDP broadcasts from
IPv6 clients to the DHCPv6 server. You can configure multiple helper addresses on an interface by repeating the
same command for each DHCPv6 server address. The no version of this command deletes the IPv6 helper
address.
Example
OS10(config)# interface ethernet 1/1/22
OS10(conf-if-eth1/1/22)# ipv6 helper-address 2001:db8:0:1:1:1:1:1 vrf blue
