After discovering and creating the BGP topology objects in its repository, Network Protocol Manager for BGP monitors the status of the BGP objects by periodically establishing SNMP sessions to the managed devices and polling the BGP4 MIB objects that are listed in Instrumentation MIB objects polled by NPM for BGP (IPv4).
