Table 3-4		Common Command Modes and CLI Prompts (continued)
Command Mode			Description
Router submode			Router configuration submodes are accessed from router configuration mode. The following
configuration			command syntax is used for entering router address family configuration submode:
			RP/0/RSP0/CPU0:router(config)# router ospf 100
			RP/0/RSP0/CPU0:router(config-ospf)# security ttl
			For more information, see the following Cisco Systems documents:
			• Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide
			• Cisco ASR 9000 Series Aggregation Services Router Routing Command Reference
ROM Monitor			The ROM Monitor is a bootstrap program that initializes the hardware and boots the system when a
(ROMMON) mode			router is powered on or reset. ROM Monitor mode is also known as “ROMMON,” which reflects the
			CLI prompt for the mode.
			rommon B1>
			During normal operation, users do not interact with ROMMON. This mode is accessed only by
			manually interrupting the boot process and placing the system in ROMMON. Once in ROMMON,
			you can perform ROM Monitor tasks, including reinstallation of the Cisco IOS XR Software,
			password recovery, and other diagnostic tasks.
			The ROM Monitor CLI mode is accessible only from a terminal connected directly to the Console
			port of the primary RSP, a terminal-modem connection to the AUX port, or through a terminal server.
			See Cisco ASR 9000 Series Aggregation Services Router ROM Monitor Guide for information and
			instructions on using ROM Monitor mode.

Entering EXEC Commands from a Configuration Mode

EXEC commands can be executed from any configuration mode by preceding the command with the do keyword. Executing EXEC commands from a configuration mode allows you to view the state of the system without exiting the configuration mode. For example:

RP/0/RSP0/CPU0:router(config)# do show version
