300-410 Practice Question: Given this configuration on Router R5: route-map…
Given this configuration on Router R5:
route-map OSPF-to-EIGRP permit 10 match ip address prefix-list EIGRP-ONLY set metric 10000 100 255 1 1500 !
router eigrp 100
redistribute ospf 1 route-map OSPF-to-EIGRP
What is the purpose of the route-map in 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
✓
The route-map filters OSPF routes based on the prefix-list and sets the metric for matching routes.
The route-map is used to filter which OSPF routes are redistributed into EIGRP (via the prefix-list) and to set the metric for those routes. Only routes matching the prefix-list will be 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.
- ✗
The route-map sets the metric for all redistributed OSPF routes, but does not filter any routes.
Why it's wrong here
The route-map includes a match clause, so it filters routes.
- ✓
The route-map filters OSPF routes based on the prefix-list and sets the metric for matching routes.
Why this is correct
The match ip address prefix-list filters, and the set metric assigns the metric.
- ✗
The route-map is applied to inbound EIGRP updates, not to redistribution.
Why it's wrong here
The route-map is used in the redistribute command, so it affects redistribution.
- ✗
The route-map will deny all routes because there is no 'permit' statement for the prefix-list.
Why it's wrong here
The route-map has a permit statement; the prefix-list will determine which routes are matched.

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.
