300-410 Practice Question: Examine the following OSPF configuration on…
Examine the following OSPF configuration on router R1:
router ospf 1 network 10.0.0.0 0.255.255.255 area 0 network 192.168.1.0 0.0.0.255 area 1
What is the effect of this configuration?
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
✓
All interfaces with IP addresses in the 10.0.0.0/8 range will be enabled for OSPF in area 0, and interfaces in 192.168.1.0/24 will be in area 1.
The network statements define which interfaces participate in OSPF and assign them to areas. The first statement covers all interfaces with IP addresses starting with 10.x.x.x, and the second covers 192.168.1.x. This is a valid configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
All interfaces with IP addresses in the 10.0.0.0/8 range will be enabled for OSPF in area 0, and interfaces in 192.168.1.0/24 will be in area 1.
Why this is correct
Correct. The wildcard mask 0.255.255.255 matches the first octet, and 0.0.0.255 matches the last octet.
- ✗
Only the interface with IP 10.0.0.1 will be in area 0; all other 10.x.x.x interfaces are ignored.
Why it's wrong here
Incorrect. The wildcard mask 0.255.255.255 matches all addresses starting with 10.
- ✗
The configuration is invalid because OSPF process 1 cannot have two network statements in different areas.
Why it's wrong here
Incorrect. OSPF can have multiple network statements in different areas.
- ✗
The configuration will cause a routing loop between area 0 and area 1.
Why it's wrong here
Incorrect. There is no loop; area 0 is the backbone, and area 1 is a regular area.

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.
