350-401 Practice Question: Drag and drop the steps of MPLS Traffic…
Drag and drop the steps of MPLS Traffic Engineering (TE) tunnel setup (RSVP) 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
IGP floods TE link attributes (bandwidth, affinity)
MPLS TE tunnel setup using RSVP begins with IGP extension (OSPF/IS-IS) to flood TE link attributes, then CSPF computes the path, RSVP Path message is sent, RSVP Resv message reserves resources, and finally the tunnel is signaled and installed in the forwarding table.

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.
