A network engineer runs the following command on Router R3:
R3# 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 Add State UpDn Tm Attrb
----- --------------- --------------- ----- -------- ----- 1 192.168.1.1 10.0.0.1 UP 00:12:34 D 1 192.168.1.2 10.0.0.2 UP 00:10:20 D
Based on this output, what can be concluded?
⚠ Common exam trap
Cisco often tests the distinction between Hub and Spoke roles in DMVPN output; candidates mistakenly assume any router with multiple peers must be a spoke, but the 'Type:Hub' field and dynamic attribute entries clearly identify the hub role.
Answer choices
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
✓
There are two active spoke routers connected to this hub.
The output shows the router is a Hub (Type:Hub) with two NHRP peers (NHRP Peers:2), both in the UP state with dynamic (D) attribute entries. This confirms that two spoke routers have successfully registered with this hub via NHRP, making option B correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
This router is a spoke in the DMVPN network.
Why it's wrong here
The output shows 'Type:Hub', so this router is configured as a hub.
- ✓
There are two active spoke routers connected to this hub.
Why this is correct
Two peers are listed with UP state, both dynamically registered, indicating two active spokes.
- ✗
The tunnel interface is down because no peers are listed.
Why it's wrong here
Peers are listed and the state is UP, so the tunnel is operational.
- ✗
The router is using static NHRP mappings for all peers.
Why it's wrong here
The 'D' attribute indicates dynamic mappings, not static.
