What is the default seed metric used by Cisco IOS when redistributing routes into RIP?
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
✓
0
By default, RIP assigns a seed metric of 0 to redistributed routes, which makes them unreachable unless a metric is explicitly configured.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
0
Why this is correct
RIP uses a default metric of 0 for redistributed routes, meaning they are not advertised until a metric is set.
- ✗
1
Why it's wrong here
A metric of 1 is not the default; it must be manually configured to make redistributed routes reachable.
- ✗
15
Why it's wrong here
15 is the maximum hop count in RIP, not the default seed metric.
- ✗
16
Why it's wrong here
16 indicates an unreachable route in RIP, but the default seed metric is 0, not 16.

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.
