Some cluster configurations give each Route Reflector the same Cluster-ID, while others assign a unique ID to each one. In a cluster configuration, each Route Reflector has a Cluster-ID (a four-byte string that can be manually configured or taken from the Router ID). If the Route Reflector crashes, the entire network will be affected.Ĭlustering Route Reflectors is a standard solution to that problem. However, it also creates a single point of failure. The nested autonomous systems are also forming eBPG peerings between themselves and thus avoid using Route Reflectors.Ī Route Reflector simplifies an iBGP network when it comes to route propagation. A confederation employs nested autonomous systems into the original AS and is also advertised as a single AS to external peers.
