300-410 Exam - Question 264


In a DMVPN network, the Spoke1 user observed that the voice traffic is coming to Spoke2 users via the hub router. Which command is required on both spoke routers to communicate directly to one another?

Show Answer
Correct Answer: BD

In a DMVPN network, when spoke routers need to communicate directly with each other without routing traffic through the hub, the command 'ip nhrp redirect' is required on the hub, and the command 'ip nhrp shortcut' is required on the spokes. However, the question specifically asks for a command required on both spoke routers. Therefore, 'ip nhrp shortcut' is correctly suggested. The 'ip nhrp redirect' command should be configured on the hub, but in this context, the shortcut command on the spokes is the correct and complete answer.

Answer is correct. Question is what config is required on both spokes. So not the config on the hub is requested.
