Border Gateway Protocol (BGP) Persistent Route Oscillation Condition
D. McPherson, Vijay Gill, Daniel Walton, A. Retana · 2002
In particular configurations, the scaling mechanisms defined in Route Reflection - An Alternative to Full Mesh IBGP and Autonomous System Confederations for BGP will introduce persistent route oscillation. This document discusses the two types of persistent route oscillation that have been identified, describes when these conditions will occur, and provides some network design guidelines to avoid introducing such occurrences.
