Cisco ROUTE 2.0: Network Principles and Layer 2 Technologies

Anyone wishing to obtain real-world routing knowledge, and those that are considering CCNP and CCIP certification. This learning path’s discussion of routing could also benefit early CCIE Routing and Switching candidates. Students completing the ROUTE 2.0 learning path should have a solid foundation in routing fundamentals, Cisco IOS basics, and Cisco routing basics. Attending the ICND1 and ICND2 classes or having the CCNA certification will fulfill these expectations.

Understanding the purpose of some of the commonly used Layer1 and Layer 2 technologies, as well as network protocols, is central to understanding how hosts communicate with one another. LANs have rapidly evolved into support systems that are critical to communications within an organization and it is important to understand how these systems operate. In this course you will learn about data transport methods, packet flows, and packet management for IPv4 and IPv6. You will also learn about Layer 2 technologies such as the Point-to-Point Protocol (PPP) and Frame Relay and their operations.


Network Principles

  • start the course
  • compare reliable and best-effort transport
  • match the TCP and UDP protocol to its characteristics
  • explain how sequence numbers are used in TCP and UDP flows
  • describe TCP send and receive behavior
  • recognize what happens as a result of multiple TCP drops in the same session
  • describe how global synchronization is a tail drop limitation
  • describe asymmetric routing
  • explain the purpose of ICMP unreachables and redirects
  • recognize when IPv4 fragmentation is required
  • recognize the function of maximum segment size (MMS)
  • explain how large packets are managed in IPv6 networks
  • describe the function of the time to live (TTL)
  • match the latency type to its description

Layer 2 Technologies

  • describe the PPP architecture
  • configure a serial link for PPP
  • describe how PPP is carried over Ethernet
  • sequence the tasks to configure the CPE as the PPPoE client
  • describe the basic functionality of Frame Relay
  • describe Frame Relay LMI signaling and mapping
