300-410 Practice Question: Runs the following command to verify OSPF…
A network engineer runs the following command to verify OSPF database on a DMVPN hub:
R1# show ip ospf database router 2.2.2.2
OSPF Router with ID (1.1.1.1) (Process ID 1)
Router Link States (Area 0)
LS age: 100 Options: (No TOS-capability, DC) LS Type: Router Links Link State ID: 2.2.2.2 Advertising Router: 2.2.2.2 LS Seq Number: 80000001 Checksum: 0x1234 Length: 48 Number of Links: 1
Link connected to: a Transit Network (Link ID) Designated Router address: 10.0.0.1 (Link Data) Router Interface address: 10.0.0.2 Number of MTID metrics: 0 TOS 0 Metrics: 10
What does this output indicate?
⚠ Common exam trap
The trap is misreading the Link ID as the router's own address rather than the DR's address — candidates must remember that on transit network links, the Link ID field carries the DR's interface IP, not the advertising router's.
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
✓
The router 2.2.2.2 is connected to the DR at 10.0.0.1 over the DMVPN tunnel with cost 10.
The output shows a Router LSA (Type 1) for router 2.2.2.2 with one link: a transit network whose Designated Router is 10.0.0.1 and whose local interface address is 10.0.0.2, with a TOS 0 metric (cost) of 10. This indicates 2.2.2.2 is attached to a multi-access transit network (the DMVPN tunnel) via 10.0.0.2, with the DR at 10.0.0.1, and the link cost is 10.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The router 2.2.2.2 is advertising a stub network via Tunnel0.
Why it's wrong here
The link is coded as a Transit Network pointing to a designated router, not a stub network, which would appear as 'a stub network' with a subnet link ID. It is tempting because stub links also show one link and a metric, but the Link ID field here is a DR address, not a network prefix.
- ✓
The router 2.2.2.2 is connected to the DR at 10.0.0.1 over the DMVPN tunnel with cost 10.
Why this is correct
The Router LSA shows a single link to a Transit Network, with the DR at 10.0.0.1 and the advertising router's interface address 10.0.0.2, carrying TOS 0 metric 10. This confirms 2.2.2.2 reaches the DR across the DMVPN tunnel at cost 10.
- ✗
The router 2.2.2.2 is the DR for the DMVPN network.
Why it's wrong here
The DR address is 10.0.0.1, while 2.2.2.2 appears only as the advertising router and interface address 10.0.0.2, so it is not the DR. It is tempting because the LSA is generated by 2.2.2.2, but advertising an LSA does not make a router the designated router.
- ✗
The OSPF database is empty; no LSAs have been received.
Why it's wrong here
The output clearly displays a populated Router LSA with sequence number, checksum and link details, so the database is not empty. It is tempting because a single LSA entry may look sparse, but an empty database would return no LSA output at all for that router ID.
Visual reference
Quick reference
Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.
