Aroute is reflected by an RR from a client to another client. If an RR and a client arefully connected, you can disable the reflection 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 isused to identify the cluster. Configuring multiple RRs can improve the networkstability. If there are multiple RRs in a cluster, use related command to configurethe same cluster ID for them to avoid routing loopback.6.7.5 Configuring BGP ConfederationFollow these steps to configure BGP confederation:To do...
