300-410 Practice Question: Drag and drop the steps to verify and validate…
Drag and drop the steps to verify and validate the operational state of an IPv6 tunneling technique into the correct order, from first to last.
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
Check tunnel interface status with 'show interfaces tunnel0'
Validation follows a systematic approach: start with checking the tunnel interface status and counters, then verify IPv6 connectivity across the tunnel using ping, examine routing protocol adjacency over the tunnel, validate end-to-end IPv6 reachability to remote networks, and finally confirm traffic flow with traceroute or debug commands.
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.
