Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 600

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?

Answer options

• A. ip nhrp nhs multicast
• B. ip nhrp shortcut
• C. ip nhrp map dynamic
• D. ip nhrp redirect

Correct answer: B

Explanation

The correct command, 'ip nhrp shortcut', allows spokes to communicate directly with each other by creating a shortcut in the NHRP mapping. The other options do not facilitate direct communication between spoke routers; for instance, 'ip nhrp nhs multicast' is related to multicast NHRP, while 'ip nhrp map dynamic' and 'ip nhrp redirect' serve different purposes in NHRP routing.
