CCNP Practice Question: Examine the following OSPF configuration on a…
Examine the following OSPF configuration on a Cisco IOS-XE router:
router ospf 1
router-id 1.1.1.1
network 10.0.0.0 0.255.255.255 area 0 network 192.168.1.0 0.0.0.255 area 1
default-information originate always metric 10 metric-type 1
What is the effect of the 'default-information originate always' command?
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
✓
A default route is unconditionally advertised into OSPF with metric 10 and type E1.
This command injects a default route (0.0.0.0/0) into the OSPF domain unconditionally, even if the router does not have a default route in its routing table. The metric and type are set as specified.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A default route is advertised into OSPF only if the router has a default route in its routing table.
Why it's wrong here
The 'always' keyword forces advertisement regardless of the presence of a default route.
- ✓
A default route is unconditionally advertised into OSPF with metric 10 and type E1.
Why this is correct
The 'always' keyword ensures unconditional advertisement, and metric-type 1 means E1.
- ✗
The router will redistribute static default routes into OSPF.
Why it's wrong here
This command originates a default route, not redistribution.
- ✗
The router will generate a default route only for area 1.
Why it's wrong here
The default route is injected into the OSPF domain, affecting all areas.

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.
