Question

The partial configuration that is shown was used to configure router on a stick for VLANS 10, 30, and 50. However, testing shows that there are some connectivity problems between the VLANs. Identify which configuration error is causing this problem.

Answer 1

The missing command to enable router to route between the VLANs is causing the connectivity problems.

Step-by-step explanation:

The configuration error that is causing the connectivity problems between the VLANs is the missing command to enable the router to route between the VLANs. In order to enable inter-VLAN routing, the command ip routing needs to be added to the global configuration mode. This command allows the router to forward packets between different VLANs.

Without this command, the router will only be able to handle traffic within each individual VLAN, but not between them. Therefore, the VLANs will not be able to communicate with each other.

1. First, enter global configuration mode by typing configure terminal.
2. Next, enable inter-VLAN routing by typing ip routing.
3. Finally, exit the global configuration mode by typing exit.
