Question

A. show ip interface brief
B. show ip route
C. show running-config
D. show cdp neighbors
E. show protocols
Answer
C. show running-config
Explanation
The show running-config command helps confirm if the ip routing feature is enabled on the router.
The command to verify if IP routing is enabled on a Cisco router is show running-config.
- The show running-config command displays the current configuration of the router, including whether the ip routing feature is enabled or disabled.
- On Cisco routers, IP routing is enabled by default. If it has been disabled, you will see the line no ip routing in the running configuration. If you do not see no ip routing, then IP routing is active.
- On Layer 3 switches, you must explicitly enable IP routing with the ip routing command in global configuration mode. The running configuration will reflect this setting.
- To quickly check, use show running-config | include routing to filter for routing-related lines.
show running-config reveals whether IP routing is enabled or disabled by displaying the presence or absence of the ip routing or no ip routing command in the configuration. This is the definitive method to verify the router's routing capability.
