300-410 Practice Question: Consider the following configuration on Router…
Consider the following configuration on Router R4:
router eigrp 100
redistribute ospf 1 metric 10000 100 255 1 1500
router ospf 1
redistribute eigrp 100 metric 20 metric-type 1 subnets
What is a potential issue with 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
✓
Mutual redistribution without route filtering can cause routing loops or suboptimal routing.
Mutual redistribution without route filtering or administrative distance adjustments can cause routing loops or suboptimal routing. The configuration does not include any route-maps or distribute-lists to control which routes are redistributed, which is a common pitfall.
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 configuration is correct and will work without issues.
Why it's wrong here
Mutual redistribution without filtering can lead to loops.
- ✗
The 'metric-type 1' in OSPF redistribution may cause EIGRP routes to be preferred over OSPF routes.
Why it's wrong here
The metric type does not directly cause preference issues; it's the lack of filtering that is problematic.
- ✓
Mutual redistribution without route filtering can cause routing loops or suboptimal routing.
Why this is correct
Without filtering, routes can be redistributed back and forth, causing loops.
- ✗
The EIGRP metric values are invalid because load must be between 1 and 255.
Why it's wrong here
The load value of 1 is valid (range 1-255).

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.
