Configuration

IPv6 DHCPv6 Relay Agent is enabled, but is not configured with the IPv6 address of a DHCP server.

IPv6 DHCPv6 Relay Agent must be configured with the address of at least one DHCPv6 server. Without a DHCPv6 server, DHCPv6 Relay Agent has nowhere to relay DHCP messages from clients.

The IPv6 DHCP Relay Agent listens for DHCPv6 broadcast packets sent on a subnet, and forwards them as a unicast packet to a DHCPv6 server on a different subnet. You must configure the IPv6 address of the DHCPv6 server to which the agent forwards the requests.

Use 'Routing and Remote Access' in Server Manager to configure one or more DHCP server addresses on the IPv6 DHCPv6 Relay Agent Properties page.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

  1. Start Server Manager. Click Start, click Administrative Tools, and then click Server Manager.

  2. In the navigation tree, expand Roles, expand Network Policy and Access Services, expand Routing and Remote Access, and then expand IPv6.

  3. Right-click DHCPv6 Relay Agent, and then click Properties.

  4. On the Servers tab, type the IPv6 address for the DHCPv6 server in the Server address box, and then click Add. Add additional DHCP servers for fault tolerance.

  5. Click OK to save your changes.
