How to Identify DMVPN Hub and Spoke Roles Using show dmvpn
This 300-410 practice question tests your understanding of dmvpn. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer runs the following command on Router R1:
R1# show dmvpn
Legend: Attrb -> S: Static, D: Dynamic, I: Incomplete N: NATed, L: Local, X: No Socket #Ent -> Number of NHRP entries with same NBMA peer NHS Status: E => Expecting Replies, R => Responding, W => Waiting UpDn Time -> Up or Down Time for a Tunnel ==========================================================================
Interface: Tunnel0, IPv4 NHRP Details
Type:Hub, NHRP Peers:2,
# Ent Peer NBMA Addr Peer Tunnel Addr State UpDn Tm Attrb
----- --------------- ---------------- ----- -------- ----- 1 10.1.1.2 172.16.0.2 UP 00:02:15 D 1 10.1.1.3 172.16.0.3 UP 00:01:45 D
Based on this output, which statement is correct?
Quick Answer
The answer is that Router R1 is a hub with two dynamically registered spokes. This is correct because the show dmvpn output explicitly lists the tunnel interface type as “Hub” and displays two NHRP peers with the “D” attribute, indicating they registered dynamically rather than being statically configured. In DMVPN, the hub maintains a static NHRP mapping for itself, while spokes register their NBMA and tunnel addresses dynamically upon connection, which is exactly what the “Attrb” column confirms here. On the Cisco CCNP ENARSI 300-410 exam, this command tests your ability to interpret NHRP peer states and distinguish hub versus spoke roles; a common trap is confusing the “D” attribute for “down” when it actually means “dynamic.” A quick memory tip: “Hub has the Type, Spokes have the D” — the hub’s role is labeled directly, while dynamic entries always belong to spokes.

Correct answer & explanation
✓
Router R1 is a hub with two dynamically registered spokes.
The show dmvpn command displays NHRP peers. The output shows two dynamic peers (D) with their NBMA and tunnel addresses. The hub has two spokes registered, both in UP state. The correct answer identifies the role and peer count.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A network engineer runs the following command on Router R1: R1# show dmvpn detail Legend: Attrb -> S: Static, D: Dynamic, I: Incomplete N: NATed, L: Local, X: No Socket #Ent -> Number of NHRP entries with same NBMA peer NHS Status: E => Expecting Replies, R => Responding, W => Waiting UpDn Time -> Up or Down Time for a Tunnel ========================================================================== Interface: Tunnel0, IPv4 NHRP Details Type:Spoke, NHRP Peers:1, # Ent Peer NBMA Addr Peer Tunnel Addr State UpDn Tm Attrb ----- --------------- ---------------- ----- -------- ----- 1 10.1.1.1 172.16.0.1 UP 00:10:00 S Based on this output, what is the problem?
medium- ✓ A.The spoke has a static NHRP mapping for the hub, which is correct for phase 1 DMVPN.
- B.The spoke has dynamically learned the hub.
- C.The hub is not reachable.
- D.The spoke is configured as a hub.
Why A: The output shows a spoke router with a single NHRP peer (the hub) marked as static (S). In DMVPN phase 1, spokes only have static mappings for the hub and do not form dynamic spoke-to-spoke tunnels. Therefore, this output is normal and indicates correct configuration for phase 1 DMVPN. There is no problem.
