Correct answer & explanation
✓
Edge device learns local routes via connected/static/dynamic
In OMP, the sequence starts with the edge device learning routes locally (connected, static, or dynamic), then redistributing them into OMP and sending to vSmart. vSmart processes and installs routes in its RIB, then advertises the best routes to other edge devices. The receiving edge device installs the route in its forwarding table and optionally redistributes into its local routing protocol.
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.
