Description (partial)

Two paths can be advertised with the same path-id in BGP add-path. This will cause the receiver to delete the first path with that path-id.

When using add-path and more than 2^32 updates of a particular prefix are received. In order to be counted, the received update must be advertised again as an additional path to our neighbors.
