_________________ is an easy command to show configuration for RIP and the other networks that have been configured. It also serves as a starting point for troubleshooting an existing implementation of RIP. It serves well when misconfigured or missing network statements are a likely situation.
Definition
show running- config
Term
This command makes sure that RIP updates are received from neighbors. It also shows that the network configuration is functioning as the entries are reflected in the routing table.
Definition
show ip route
Term
This command helps to see all the IP routing protocols that have been configured on a routing device.
Definition
show ip protocols
Term
This command helps to see real-time updates as they are being sent and received for RIP.
Definition
debug ip rip
Term
The _________________ command (Global Configuration)enables manipulation of fields and alteration of normal default operations of the router.
Definition
config-register
Term
This command can optionally be used to instruct the bootstrap to boot from specific locations. This command can even be used to specify which file to load in case of multiple IOS files on that location.
Definition
Boot system
Term
What would be the command to change a router's hostname to CCNA2222
Definition
Router(config) #hostname CCNA2222
Term
__________ is also known as the message of the day.
Definition
Login Banner
Term
____ is used as a delimiting character to inform the IOS the beginning and the end of the banner.
Definition
#
Term
The primary function of Cisco routers and switches is _______________.
Definition
transferring data between interfaces
Term
The command ____________ is used to designated ip addresses. The syntax is that the assigned address for the interface and subnet mask should follow the command.
Definition

Term
By default all router interfaces are in a ________ state.
Definition
disabled
Term
The configuring administrator has to enable the interface by using the command ___________.
Definition

Term
The configuration to set duplex and speed manually is:
Definition
Router(config) #interface FastEthernet 0/0
