300-410 Practice Question: Runs the following command on Router R1: R1# show…
A network engineer runs the following command on Router R1:
R1# show dmvpn Interface: Tunnel0, IPv4 NHRP Details
Type:Hub, NHRP Peers:2,
# Ent Peer NBMA Addr Peer Tunnel Add State UpDn Tm Attrb
----- ----------------- --------------- ----- -------- ----- 1 10.0.0.2 10.1.1.2 UP 00:10:00 D 2 10.0.0.3 10.1.1.3 UP 00:05:00 D
Based on this output, what is the role of Router R1 in the DMVPN network?
⚠ Common exam trap
Cisco often tests the distinction between the 'Type:Hub' and 'Type:Spoke' fields in the show dmvpn output, and candidates may misinterpret the 'D' attribute as meaning the router is a spoke or that the tunnel is down, when it actually indicates a dynamic peer relationship on the hub.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Router R1 is the hub router with two active spoke connections.
The output shows that Router R1 has a Tunnel0 interface configured as a DMVPN hub (Type:Hub) with two NHRP peers (10.1.1.2 and 10.1.1.3) in the UP state. The 'D' attribute in the Attrb column indicates these peers are directly connected spokes, confirming R1 is the hub router with two active spoke connections.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Router R1 is the hub router with two active spoke connections.
Why this is correct
The 'Type:Hub' and two UP peers indicate it is a hub.
- ✗
Router R1 is a spoke router with two hub connections.
Why it's wrong here
The type is Hub, not Spoke.
- ✗
Router R1 is a spoke router with two other spoke connections.
Why it's wrong here
The type is Hub, and spokes connect to hubs.
- ✗
Router R1 is not participating in DMVPN because the tunnel is down.
Why it's wrong here
The tunnel is up, as indicated by the UP state of peers.
