IES-L3 Layer 3 Networking

This course will introduce you to a variety of routing protocols; extending your knowledge of VLAN technologies. During this hands on course, you will be trained to configure L3 switches in WAN infrastructures.


 

Content


Short Network Introduction

  • Typical network (WAN infrastructures)
  • L2 redundancy protocols [RSTP/ Turbo Ring / Turbo Chain]
  • L3 switches vs routers

L3 Networking

  • VLAN & Inter-VLAN routing [IP interface]
  • L3 routing
  • Static routing
  • Dynamic routing
  • Unicast routing protocols [RIP / OSPF]
  • Multicast routing protocols [DVMRP / PIM-DM]
  • L3 Node redundancy [VRRP]

Hands-on Training Including

  • L2 redundancy configuration
  • VLAN
  • Inter-VLAN [Interface setup]
  • Static routing
  • Unicast dynamic routing [RIP, OSPF]
  • Optional multicast routing [DVMRP/PIM-DM]
  • VRRP

Prerequisistes

Extended knowledge in networking is required, based on long experiences in the field or previous attendance of the “Layer 2 Networking” (IES-L2) course.


Learning Objectives


This course covers the following:

TCP/IP protocol and general concept

  • Explain the difference between “connection oriented” and “connectionless” mechanisms
  • Explain the concept of TCP/IP protocol suite
  • Describe the roles and mechanisms in each communication layer
  • Describe which networking devices operates in which communication layer
  • Understand the PDU format in Ethernet frame and IP packet
  • Explain how error detection in Ethernet works
  • Describe the difference between “store and forward” and “cut through” mechanism
  • Explain the concept of ”Power over Ethernet” and its standards

Ethernet and IP addressing

  • Explain the interaction of MAC address and IP address
  • Explain IPv4 classes and subnets
  • Calculate IP range, subnet ID and broadcast address in IPv4
  • Explain the interaction of “packet switch communication” and “unicast/ multicast/ broadcast communication”

Application Protocols

  • Understand basic concept of well-known protocols e.g.
  • DHCP, ICMP, ARP and SNMP
