Table 3-4	Common Command Modes and CLI Prompts (continued)
Command Mode		Description
administration		Administration configuration mode allows you to assign system resources to RSPs.
configuration mode		From administration EXEC mode, use the configure command to enter administration configuration
		submode:
		RP/0/RSP0/CPU0:router(admin)# configure
		RP/0/RSP0/CPU0:router(admin-config)#
Global configuration		Global configuration mode is the starting point for RSP configuration. Commands entered in this
		mode affect the RSP as a whole, rather than just one protocol or interface. Global configuration mode
		is also used for entering configuration submodes to configure specific elements, such as interfaces
		or protocols.
		To enter global configuration mode, type the configure command at the EXEC command prompt:
		RP/0/RSP0/CPU0:router# configure
		RP/0/RSP0/CPU0:router(config)#
		Note The system prompt changes to “router(config)” to indicate that the router is now in global
		configuration mode.
Configuration		From the global configuration mode you can enter more specific command modes. These are
submodes		available based on your access privileges and include protocol-specific, platform-specific, and
		feature-specific configuration modes.
		In the following example, MPLS LDP configuration mode is entered from global configuration
		mode. The prompt for MPLS LDP configuration submode appears as config-ldp. The following
		command syntax is used for entering configuration MPLS LDP submode:
		RP/0/RSP0/CPU0:router# configure
		RP/0/RSP0/CPU0:router(config)# mpls ldp
		RP/0/RSP0/CPU0:router(config-ldp)#
		Note The availability of any particular mode depends on the router features and the access rights
		of the individual user. For example, a configuration mode for configuring access servers is
		not available on most routers.
Interface configuration		The interface configuration submode is used to select and configure a hardware interface. To enter
		interface configuration mode from global configuration mode, use an interface command. An
		interface configuration command always follows an interface global configuration command, which
		defines the interface type.
		RP/0/RSP0/CPU0:router(config)# interface tunnel-te 2
		RP/0/RSP0/CPU0:router(config-if)#
Router configuration		The router configuration submode is used to select and configure a routing protocol, like OSPF, or
		IS-IS. The following command syntax is used for entering router configuration submode: router
		protocol [protocol_options]
		Replace protocol with the keyword for the protocol you want to configure. Replace protocol_options
		with any keywords and arguments required for that protocol.
		RP/0/RSP0/CPU0:router(config)# router ospf 100
		RP/0/RSP0/CPU0:router(config-ospf)#
