Abstract:
1. A method in a system including a first autonomous system (AS) configured to have a first gateway router forward data associated with a set of Internet Protocol (IP) address prefixes, to a second AS via a first link to a first external border gateway protocol (eBGP) peer device of the second AS, the method comprising: a) receiving information about data packets dropped at an output of the first gateway router and associating the received information with the set of IP address prefixes; b) determining whether a data traffic offload condition exists using the received information; c) changing one or more path attributes of at least some of the IP address prefixes of the set, responsive to the determination that a data traffic offload condition exists, such that the first gateway router will be less likely to forward data associated with the at least some of the IP address prefixes of the set; and d) generating a BGP update message including the changed one or more path attributes for communication to at least one internal border gateway protocol (iBGP) peer device in the first AS.
