 *Routes received from:
- Route-Reflector-client is reflected to other clients and non-client neighbors
+ RR-client is reflected to other clients and non-client neighbors
  Non-client neighbors are reflected to Route-Reflector-client neighbors only
+*An RR reflecting the route received from a RR-Client adds:
-*Sets the '''Originator-ID''' attribute in the reflected update if it is not already set.
-*Adds the Cluster-ID to the Cluster-list attribute in the reflected update.
+ Originator ID - Router ID of the originator of the route in the local AS.
+                 If the update comes back to the originator, it ignores the update.
+ Cluster List - Router ID of RR. A list of Cluster IDs that an update has traversed.
+                When a RR sends a route received from a client to a non-client, it appends the local Cluster ID.
+                If a RR receives a route whose Cluster List contains the local Cluster ID, it ignores the update.
 *RR reflects routes considered as best routes only.
 *If more than one update is received for the same destination only the BGP best route is reflected.
