CCNP Practice Question: Drag and drop the steps of MPLS traffic…
Drag and drop the steps of MPLS traffic engineering (MPLS-TE) tunnel setup 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
Configure IGP with TE extensions (OSPF TE or IS-IS TE)
First, IGP must be configured with TE extensions (e.g., OSPF TE) to flood link attributes. Then MPLS-TE is enabled on interfaces. The headend router computes a path using CSPF based on constraints. The tunnel interface is configured with the destination and constraints. Finally, RSVP-TE signals the LSP and reserves bandwidth along the path.

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.
