Abstract
Autoconfiguration of an IPv6 component in a segmented network including receiving an IPv6 packet; determining whether the received IPv6 packet is a router advertisement or a router solicitation; if the received IPv6 packet is a router advertisement, then retrieving through an out-of-band link a MAC address for the IPv6 component, removing a MAC address of a sending router, inserting in the packet instead an internal MAC address for forwarding packets to the IPv6 component, removing a multicast destination MAC address, inserting in the packet the destination MAC address of the IPv6 component, and forwarding the packet to the IPv6 component as a unicast message; if the received IPv6 packet is a router solicitation, then removing the MAC address of the sending IPv6 component, inserting in the packet instead an external MAC address for forwarding packets to the router, and forwarding the packet to the router as a multicast message.
