Abstract
Techniques are described for automatically setting source address filters within a network device. For example, an apparatus, such as a router, comprises a network interface card to receive routing information from a network device. The routing information specifies at least one unselected network route to a network destination, and includes a tag associated with the unselected route to indicate that the network device does not forward outbound data along the unselected route. The apparatus further comprises a control unit to automatically set a filter to receive inbound data from the network destination specified by the non-selected route. The control unit may automatically set, for example, a source address filter.
