Abstract: BGP Route Oscillation Reduction and Deployment Considerations, by Enke Chen



In this presentation we analyze several cases of BGP persistent route oscillation, and identify the unnecessary route withdraw as the primary contributor to these cases. We present a revised approach of advertising the best external route that can be used to reduce route oscillation. Finally, we present recommendations on route oscillation detection and outline deployment considerations that would help reduce/avoid persistent route oscillations using route reflection or confederation.
