Which command shows the IPv4 routing table on a Cisco router?

• A. show ip route
• B. show ip interfaces
• C. show routes
• D. show ip protocols

Answer: (A)

To see how a Cisco router forwards IPv4 traffic, you need to view its routing table. The best command for that is show ip route, which displays all IPv4 routes the router knows—including destination networks, the next hop or exit interface, metric, and how the route was learned (connected, static, or via a dynamic protocol). This lets you understand exactly what paths the router will use to reach any IPv4 destination.

Other commands don’t show the routing table. show ip interfaces reveals per-interface IP addresses and statuses, not the routes. show ip protocols shows information about configured routing protocols themselves, not the actual routes. show routes is not the standard, reliable way to view the IPv4 routing table on modern IOS.
