Which protocol enables segment routing for traffic engineering in modern networks?

  1. OSPF
  2. BGP
  3. SR-MPLS / SRv6
  4. RIP

Answer: SR-MPLS / SRv6

Segment Routing (SR-MPLS, SRv6) encodes path instructions in packet headers, enabling flexible traffic engineering without per-flow state. Critical for scalable, programmable networks. Important for advanced networking questions.
