300-410 Practice Question: Consider the following partial configuration on…
Consider the following partial configuration on Router R1:
router eigrp 100
redistribute ospf 1 metric 10000 100 255 1 1500
router ospf 1
redistribute eigrp 100 subnets
Which statement about this configuration is true?
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
✓
Redistributed OSPF routes into EIGRP will have a default metric of 10000 100 255 1 1500.
The configuration redistributes OSPF routes into EIGRP with specific bandwidth, delay, reliability, load, and MTU metrics. The 'subnets' keyword in OSPF redistribution ensures that all subnets (including classless prefixes) are redistributed. Without 'subnets', only classful networks are redistributed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Redistributed OSPF routes into EIGRP will have a default metric of 10000 100 255 1 1500.
Why this is correct
The 'metric' keyword in the redistribute command sets the EIGRP metric for all redistributed routes.
- ✗
OSPF routes redistributed into EIGRP will have a metric of 20 by default.
Why it's wrong here
The default metric for OSPF redistribution into EIGRP is not defined; the 'metric' keyword is required or a default-metric command must be used.
- ✗
EIGRP routes redistributed into OSPF will be Type 1 external LSAs.
Why it's wrong here
By default, redistributed routes into OSPF are Type 2 external LSAs unless the 'metric-type' keyword is used.
- ✗
The 'subnets' keyword in OSPF redistribution is optional but recommended.
Why it's wrong here
Without 'subnets', only classful networks are redistributed, which is often not desired. The 'subnets' keyword is not optional if you want all prefixes.

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.
