300-410 Practice Question: An engineer configures OSPFv2 with a route-map to…
An engineer configures OSPFv2 with a route-map to set the metric on redistributed routes. After redistribution, the metric is not being set as expected. Which is the most likely explanation?
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 does not have a match statement, so it applies to no routes.
When redistributing routes into OSPF, the metric is set using the 'metric' keyword in the redistribution command or via a route-map. However, if the route-map does not explicitly match the routes, the default metric (20 for external type 2) is used. Additionally, if the route-map uses 'set metric' but the redistribution command also has a 'metric' keyword, the route-map overrides the redistribution command.
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 does not have a match statement, so it applies to no routes.
Why this is correct
Without a match statement, the route-map does not apply to any routes, and the default metric is used.
- ✗
The redistribution command uses the 'subnets' keyword, which overrides the route-map.
Why it's wrong here
The 'subnets' keyword does not affect metric setting.
- ✗
The route-map is applied to the wrong direction.
Why it's wrong here
Route-maps for redistribution are applied in the redistribution command, not directionally.
- ✗
The OSPF process is configured with 'default-metric' command, which overrides the route-map.
Why it's wrong here
The route-map overrides the default-metric command.

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.
