    Hi,

     

    Synchronization is old concept does not make sense in modern MPLS network and, most of the network equipment vendors disabled it by default, auto-summary is also disabled by default, both of these are local to the device.

     

    Route reflector add originator ID in ORIGINATOR_ID field and cluster ID in the CLUSTER_LIST field, both of these attributed can be see the BGP update messages.

    Hi,

     

    If route reflector receive same route from 2 different client, it will reflect the best route based on the BGP best path selection algorithm.

    Synchronization (obsolete) and auto-summary are local concepts, no signaling involved. Route reflectors set the cluster Id attribute in the updates.
