Show AnswerHide Answer
Correct Answer:
The correct answer is B. The configuration in option B correctly sets up a DMVPN (Dynamic Multipoint Virtual Private Network) tunnel with the proper NHRP (Next Hop Resolution Protocol) configurations needed for dynamic NBMA (Non-Broadcast Multi-Access) mapping. The physical source interfaces are correctly referenced, the NHRP network ID is specified, and the tunnel mode is set to GRE multipoint, all of which are required settings for a DMVPN setup. This ensures spoke-to-spoke connectivity via the hub.

Nov 9, 2021B - only possible answer, all other sources are incorrect and B has correct NHRP map for the hub and NHS.

Oct 22, 2022B will not allow spoke to spoke tunnel. ip nhrp map multicast dynamic and tunnel mode gre multipoint are required. I think the question would assume phase 1 already configured and working. Then would go with A to change it to phase 2

Apr 28, 2023It is hard to choose from these answers. Phase 2 would really need this on the spokes: #ip nhrp map multicast x.x.x.x (#ip nhrp map multicast dynamic -> it is configured on the HUB, so obviously incorrect) https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_conn_dmvpn/configuration/xe-16-7/sec-conn-dmvpn-xe-16-7-book/sec-conn-dmvpn-dmvpn.html

Jun 11, 2023Choosing "B" after all. - As any other answers are completely wrong. #ip nhrp map multicast x.x.x.x (NBMA of HUB) is still missing from "B".

Sep 3, 2023A is not correct, tunnel source can't be 10.0.0.1 B seems to be ok C is not correct, missing multipoint on tunnel mode gre. D is not correct, ip nhrp map multicast static is not a valid command. The correct answer is B
