• Initial Router Configuration The initial configuration of the Cisco ASR 9000 Series Aggregation Services Router is determined automatically by the software when you boot the router; you need not set up any general configuration information. Also there is no explicit configuration needed to make a particular RSP active. It becomes the active RSP when chosen automatically by the software upon boot.
