Usage
Information
In BGP, route attributes are maintained at different locations. 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 1000 routes that contain the same set of attributes, then the
cluster_id count is 1. If these 1000 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 for1000 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 back-end, as both these entries have different next-hops. If this same route is sent to a different
