Abstract
The technology described in this paper relates to negotiating and advertising border gateway protocol (BGP) prefix limits between peering network devices. By exchanging configured prefix limit values during BGP session establishment, sending and receiving devices can establish an operational prefix limit to avoid unexpected session terminations. The lowest configured limit can serve as the operational limit, or a receiving device can advertise its limit to a sending device to cap advertised routes. Subsequently, when limits are reached, newer or random prefixes for sessions, if a session is restarted or cleared, can be blocked rather than being terminated.
