This module of CCNA course is dedicated to Cisco Internetwork Operating System (IOS). Look at the boot process, connectivity options, ways to configure the devices and show basic configuration and verification commands during this section.

Functions of Routers
Switches
Bridges and Hubs
IOS and TCP/IP models
Data flow between two hosts across a network

We are now all set to explore the more interesting enhanced switching technologies including: LANs, ISL and 802.1q trunking, LAN trunking protocol (VTP), inter-LAN routing, and Voice LANs in this section.

Identify basic switching concepts of CCNA course.
Types of Switching Collision / Broadcast
Domains CAM Table
Configure and verify initial switch configuration
Switch operation (ping, telnet and ssh)
Identify enhanced switching technologies
RSTP / PVSTP Ether channels
Configure and verify VLANs / Trunking DTP / Auto negotiation
Configure and verify PVSTP operation Root bridge election / STP Modes

The most important function of routers – IP routing. This module looks at the IP routing process itself and various ways to build the routing table.

C E F Packet forwarding
Router lookup process
Describe the boot process of Cisco IOS routers
Configure and verify basic Router configuration
Configure and verify interface (serial and Ethernet)
Configure and verify Static & Default routing
Manage Cisco IOS Files Boot preferences / Cisco IOS image(s) Licensing
Differentiate methods of routing and routing protocols, Static vs Dynamic Link state
Distance Vector Administrative distance, Configure and verify OSPF (single area)
Benefit of single area Neighbour adjacencies
OSPF states
Multi area Configure OSPF v2 & OSPF v3 Router
ID Passive interface
LSA types Configure and verify EIGRP (single AS)
Feasible Distance / Feasible Successors
Administrative distance
Feasibility condition
Metric composition Router ID,
Auto summary Path selection
Load balancing (Equal & Unequal)
Passive interface InterVLAN routing (Router on a stick)
Sub interfaces Encapsulation, Configure SVI interfaces

We introduce you to first-hop redundancy protocols including VRRP, HSRP, and GLBP in this section. VRRP and HSRP are primarily used for redundancy on the first hop. GLBP is the preferred choice as it is simpler to configure for load balancing also providing gateway redundancy.

Configure and verify DHCP (IOS Router)
Configuring router interfaces to use DHCP
DHCP options
Excluded addresses
Lease time ACL (Types, Features & Applications of ACLs)
Standard Extended Named & Numbered Log option
Configure and verify ACL
Identify the basic operation of NAT
Purpose Pool Static 1 to 1
Overloading Source addressing
One way NAT Configure and verify NAT Configure and verify NTP as a client
Recognize High availability (FHRP, VRRP, HSRP & GLBP)
Configure and verify Syslog
Describe SNMP v2 & v3
