300-410 Practice Question: The default metric for an IPv6 static route…
What is the default metric for an IPv6 static route redistributed into OSPFv3?
⚠ Common exam trap
A common mix-up: candidates confuse the default metric for OSPFv3 redistributed routes (20) with the default metric for OSPFv3 intra-area routes (1) or with the default metric used by other routing protocols like EIGRP (10), leading them to select the wrong option.

Correct answer & explanation
✓
20
When an IPv6 static route is redistributed into OSPFv3, OSPFv3 assigns a default metric of 20 to external routes (type E1 or E2). This is consistent with OSPFv2 behavior, where redistributed routes (including static routes) receive a default metric of 20 unless explicitly overridden with the `metric` keyword under the `redistribute` command. Option C is correct because the default metric for redistributed static routes in OSPFv3 is 20.
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 it's wrong here
0 is not a valid default metric for redistribution.
- ✗
1
Why it's wrong here
1 is the default metric for connected routes.
- ✓
20
Why this is correct
OSPFv3 uses a default metric of 20 for redistributed routes.
- ✗
10
Why it's wrong here
10 is the default metric for RIP.
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.
