Abstract

Packets are routed from at least one internet protocol (IP) address in accordance with border gateway protocol (BGP); while carrying out the routing in accordance with the border gateway protocol (BGP), at least one border gateway protocol (BGP) attribute associated with the at least one internet protocol (IP) address is noted. A firewall policy is applied to the packets from the at least one internet protocol (IP) address based on the at least one border gateway protocol (BGP) attribute associated with the at least one internet protocol (IP) address. Techniques may be implemented, for example, on a router or on a separate firewall device coupled to a router.
