Abstract :
An oscillating routing protocol will result in increased protocol activity and may lead to increased router CPU activity and memory consumption. This case study shows that BGP peering using loopback addresses when peering EBGP between two dualhomed ASes will cause BGP to oscillate. It includes a detailed lab report in which several possible setups that will cause BGP to oscillate are presented. It also includes an oscillation event from one of the world´s largest production networks that was caused by such a setup.
