Correct answer & explanation

Spoke sends data through hub

In DMVPN Phase 3, when a spoke needs to send traffic to another spoke, it first sends data through the hub, the hub forwards the packet with a redirect, the spoke then sends an NHRP resolution request to the hub, the hub replies with the destination spoke's NBMA address, and finally the source spoke builds a direct mGRE tunnel to the destination spoke. The correct order is: spoke sends data through hub, hub sends redirect with NHRP trigger, spoke sends NHRP resolution request to hub, hub replies with destination spoke NBMA address, source spoke builds direct mGRE tunnel to destination spoke.

Variation 1. Drag and drop the steps of DMVPN Phase 3 spoke-to-spoke shortcut creation into the correct order, from first to last.

medium
  • A.Spoke sends traffic to hub for remote spoke
  • B.Hub forwards packet with NHRP redirect
  • C.Source spoke sends NHRP resolution request
  • D.Hub replies with destination spoke mapping
  • E.Source spoke builds direct tunnel to destination

Why A: In DMVPN Phase 3, when a spoke needs to reach another spoke, it first sends traffic to the hub. The hub forwards the packet with an NHRP redirect. The source spoke then sends an NHRP resolution request to the hub to get the destination spoke's NBMA address. The hub replies with the mapping, and the source spoke dynamically builds a direct mGRE tunnel to the destination spoke.
