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
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
----- --------------- --------------- ----- -------- ----- 1 192.168.1.2 10.0.0.2 UP 00:15:30 D 1 192.168.1.3 10.0.0.3 UP 00:10:20 D
Based on this output, what is the role of Router R1?
⚠ Common exam trap
The trap is that candidates may not know the exact 'Type:' field in 'show dmvpn' output and may guess based on the number of peers; the output explicitly states 'Type:Hub'.
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
✓
Router R1 is a DMVPN hub.
The 'show dmvpn' output shows 'Type:Hub' for Tunnel0, which explicitly identifies Router R1 as the DMVPN hub. Additionally, R1 has two NHRP peers (the spokes) with dynamic (D) attributes, which is the expected view from the hub. A spoke would show 'Type:Spoke' and typically list the hub as its peer.
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 a DMVPN spoke.
Why it's wrong here
The Type field reads Hub, and spokes display Type:Spoke with one NHS entry; here two dynamic peers resolve through NHRP to this router. It is tempting because spokes also hold NHRP mappings, but those point to the hub, not to multiple remote tunnel endpoints.
- ✓
Router R1 is a DMVPN hub.
Why this is correct
The output shows "Type:Hub" for Tunnel0, confirming R1 terminates the DMVPN tunnels. Both peers are dynamically learned (Attrb D), meaning spokes registered their NBMA addresses with R1 via NHRP. This satisfies the scenario's requirement to identify R1's role from the show dmvpn command.
- ✗
Router R1 is a DMVPN server.
Why it's wrong here
A DMVPN server is the hub, and the output already states Type:Hub, so this merely restates the role rather than identifying it as the question's answer format expects. It is tempting because hub and server are synonymous in DMVPN terminology, but the stem asks for the role label shown.
- ✗
Router R1 is a DMVPN client.
Why it's wrong here
The Type field reads Hub, and a hub maintains NHRP peer entries for its spokes; a client or spoke would show Type:Spoke and a single NHS mapping. It is tempting because spokes also list peers, but they point at the hub, not at multiple remote tunnel endpoints.

DMVPN Phase 2
DMVPN Phase 2 is an advanced Cisco routing technology that allows spoke routers to communicate directly with one another without sending traffic through a central hub, using dynamic routing protocols and multipoint GRE tunnels.
