Abstract
An apparatus includes a plurality of ports to receive a packet. A scope circuit determines a source scope level for a source Internet protocol version 6 (IPv6) address of the received packet. A command circuit determines whether to forward the received packet based on the source scope level. The source scope level is indicative of whether a source address is a global address or a local address.
