Question

Router R1 has two interfaces that were configured with correct IP addresses and subnet masks. Why does the show ip route command output not display any information about the directly connected networks?

Answer 1

The 'show ip route' command might not display information about directly connected networks due to issues with the interfaces, IP addressing, and routing protocol/VRF configuration.

Step-by-step explanation:

The 'show ip route' command is used to display the routing table on a router. If the command does not display any information about the directly connected networks, it could be due to the following reasons:

1. The interfaces on the router might not be in an 'up/up' state. Verify if the interfaces are operational by using the 'show interfaces' command.
2. There might be an issue with the IP addressing or subnet mask configuration on the interfaces. Double-check the IP addresses and subnet masks assigned to the interfaces and ensure they fall within the correct range and are configured correctly.
3. The interfaces might not be added to the correct routing protocol or VRF (Virtual Routing and Forwarding) instance. Check if the interfaces are included in the appropriate routing protocols or VRFs.

By troubleshooting these potential issues, you should be able to resolve the problem and have the 'show ip route' command display information about the directly connected networks.
