When attributes that correspond to multiple routes change, then attribute counts that the show ip bgp summary command displays are calculated as summations of attributes corresponding to all the associated routes. For example, if cluster_id is an attribute associated with thousand routes that contain exactly the same set of attributes, then the cluster_id count is 1. If these thousand routes are set with different attribute values with the same cluster_id, then the cluster_id count is 1000, since the same value is stored for thousand different attribute records. The attribute next-hop is a part of the BGP attribute data structure. If two peers send the same route that contains similar path attributes, then two entries are maintained in the backend, as both these entries have different next-hops. If this same route is sent to a different peer, an entry for each peer is created, as the next-hop is different. As a result, the BGP attributes count in the summary output will differ accordingly.
