A route is reflected by an RRfrom a client to another client. If an RR and a client are fully connected, you can disable thereflection between clients to reduce the cost.z Normally, there is only one RR in a cluster. In this case, the router ID of the RR is used to identifythe cluster. Configuring multiple RRs can improve the network stability. If there are multiple RRs ina cluster, use related command to configure the same cluster ID for them to avoid routing loopback.Configuring BGP ConfederationFollow these steps to configure a BGP confederation:
