Add and Edit DHCP Relay IPv6 Agent Configuration Dialog Boxes
Use the Add DHCP Relay IPv6 Agent Configuration dialog box to configure and enable a DHCPv6 relay
agent on an interface. Use the Edit DHCP Relay IPv6 Agent Configuration dialog box to update an
existing interface relay agent.
Note You cannot enable a DHCPv6 relay agent on an interface where a DHCPv6 relay server is configured.
The DHCPv6 relay agent works only with external DHCPv6 servers; it will not forward DHCPv6
requests to a security appliance interface configured as a DHCPv6 server.
The Add DHCP Relay IPv6 Agent Configuration dialog box and the Edit DHCP Relay IPv6 Agent
Configuration dialog box are virtually identical; the following descriptions apply to both.
Navigation Path
You can access the Add and Edit DHCP Relay IPv6 Agent Configuration dialog boxes from the DHCP
Relay IPv6 Page, page 51-7.
