Abstract
In a system including a first autonomous system (AS) configured to have a first gateway router forward data associated with a set of IP address prefixes, to a second AS via a link to a first eBGP peer device of the second AS, the problem of data packets dropped at an output of the first gateway router while the link is still 'up' and an eBGP session between the first gateway router and the first eBGP peer is still up, is solved by (1) receiving information about dropped data packets at an output of the first gateway router, (2) determining whether a data traffic offload condition exists using the received information, (3) changing path attribute(s) of at least some of the IP address prefixes of the set if a data traffic offload condition exists, such that the first gateway router will be less likely to forward data associated with those IP address prefixes, and (4) generating a BGP update message including the changed path attribute(s) for communication to at least one iBGP peer device in the first AS.
