Course Information

Skills Learned

Upon completion of this Cisco Design training course, students will have the knowledge to:

  • Describe and apply advanced addressing and routing solutions
  • Describe and apply advanced enterprise campus networks
  • Describe and apply WAN
  • Describe and apply security and network services
  • Describe and apply Software-Defined Access

Who Should Attend This Course

  • Individuals seeking the CCNP Enterprise certification
  • Network engineers, system administrators, network designers, and IT managers wanting greater skill in network design


There are no formal prerequisites for the CCNP Enterprise certification, but we highly recommend that students first take Cisco CCNA and Cisco CCNP Enterprise: ENCOR.

Course Outline

Routed Protocols – Addressing

  • IPv4 addressing (create plan)
  • IPv6 addressing (create plan)
  • IPv6 migration methods (determine)

Routing Protocols – Secure and scale (create design)
