Question:
Refer to the exhibit. Which DMVPN phase or phases will support a DMVPN tunnel between R5 and R6?
- Phase 1, 2, or 3
- Phase 1 and 2 only
- Phase 2 and 3 only
- Phase 3 only
Explanation: There are three DMVPN phase models: Phase 1, Phase 2, and Phase 3. The first DMVPN implementation is Phase 1. Phase 1 supports only spoke-to-hub tunnels. Traffic between spokes must traverse the hub. Phases 2 and 3 support not only spoke-to-hub tunnels, but also direct spoke-to-spoke tunnels. Only Phase 2 supports spoke-to-spoke communication between DMVPN networks or regions.
