300-410 Exam - Question 104


Refer to the exhibit. An engineer has configured DMVPN on a spoke router.

What is the WAN IP address of another spoke router within the DMVPN network?

Show Answer
Correct Answer: A

The WAN IP address of another spoke router within the DMVPN network can be identified by examining the NMBA (Non-Broadcast Multi-Access) address field in the command output. In the exhibit, there are two entries under NMBA Address with the corresponding attributes 'S' (static) and 'D' (dynamic). The static attribute 'S' signifies the hub, while the dynamic attribute 'D' denotes other spokes discovered dynamically. Hence, 172.18.46.2 with the 'D' attribute is the WAN IP address of another spoke router within the DMVPN network.

This reason being is the NMBA address is the private and the Peer is the public and the first one which is 172.18.16.2 is not is because that is the Hub configured with a static mapping as it has "S" on the end. However when the address 172.18.46.2 is learned by the spoke it places a "D" at the end

Correct answer is A. Its in the NBMA field in the output of the sh cmd. The S on the far right means that neighbor is the HUB, dynamic or D is other spokes because they are dynamically discovered.

Answer is A. The WAN IP is NBNA address, which is the device physical interface. S will be the HUB. D will be he spoke who learn the other spoke address dynamically. When you do the command "show dmvpn". The first IP address is the NBMA address and the IP address after is the Tunnel IP address.

hard to say what cisco means by "WAN IP". It points more to "inner" IP than to "outer/NBMA" IP. If we stick to fact that "WAN" is customer's wide area network, then they ask about inner IP - which is D. I don't like question where they juggle with words...

WAN address is physical address of WAN interface, not the logical address of the tunnel interface. Not sure where you see the word "inner" used. What are they juggling? Physical address is the 172.18.X.X address on the left, which is A.

Cannot be the S = Static As that will be the Hub & Peer NBMA Addr is the Outside/WAn address

Other way around. Hubs are Dynamic, so S (Static) means it's a spoke.

Disregard. Spoke-to-hub connection is S when seen on spoke side.

Answer is A IP-Address 192.168.1.4 is the tunnel interface address IP-Address 172.18.46.2 is the WAN interface address D stands for dynamic tunnel which is created between spokes

A is correct, the D flag is dynamic so that is the spoke, the hub has the S (static) flag

The option A , first the NMBA address are the wan ip address and second the NHRP registration is marked as dynamic (D). registration made to the hub are marked as static (S)
