13.4.12 BGP4 learned routes limit

A limit can be imposed on the number of BGP4 routes learned from a peer.The purpose of this limit is to avoid memory shortages in the Switch caused by excessive routing information, and to prevent a peer from being unable to learn routing information from other peers due to the volume of BGP4 routing information received from a particular peer. When this functionality is enabled, if the number of BGP4 routes learned from the specified peer exceeds a set threshold, a warning message is output. If the number of learned BGP4 routes exceeds the maximum, another warning message is output and the peer is disconnected. The disconnected peer is reconnected after a set interval or by input of the clear ip bgp operation command. The functionality can be configured so that a warning message is output when the number of learned routes exceeds the maximum, but the peer is not disconnected.
