Router Operation

The Cisco ASR 9000 Series Router are fully distributed routers using a switch fabric to interconnect a
series of chassis slots, each of which can hold one of several types of line cards. Each line card in the
Cisco ASR 9000 Series has integrated input/output (I/O) and forwarding engines, plus sufficient control
plane resources to manage line card resources. Two slots in the chassis are reserved for RSP cards to
provide a single point of contact for chassis provisioning and management.
