Master network basics, including ip and mac addresses, the seven osi layers, vlan setup with router on a stick, spanning tree, etherchannel, dhcp, and hsrp redundancy.
Explore network topology with Cisco packet tracer, a simulator by Cisco. Compare it with Gns3 or DNS three, learn VLAN commands, and use Notepad for efficient configuration.
Explore the OSI model from the physical to the application layer, covering mac addresses, switches, IP addressing, TCP and UDP, and key protocols like HTTP, DNS, and DHCP.
Explore vlan theory at layer 2 to create separate broadcast domains using 802.1q tagging and access or trunk ports with basic vlan configuration on switches.
Explore inter-VLAN routing with router on a stick, creating subinterfaces such as gigabit0/0.10 and gigabit0/0.20, and configuring dot1q encapsulation and trunk ports to enable cross-VLAN communication.
Learn how DHCP automatically assigns and manages IP addresses, subnet masks, default gateways, and DNS. Explore configuring DHCP pools, exclusions, and IP helper addresses.
Configure VLAN ten and VLAN twenty, set up inter-VLAN routing via router on a stick, and create DHCP pools with relay for VLAN ten and VLAN twenty; verify IP assignment.
Etherchannel combines two to eight physical links into one logical link to increase capacity and redundancy, using port aggregation, Pagp or Lacp, with consistent speed, duplex, and port settings.
Demonstrates practical etherchannel setup across switches using Pagp and static modes, configuring vlan 10 and 20, trunk ports, and rapid pvst for balanced links with load sharing.
Explore hsrp, a Cisco protocol that provides layer 3 redundancy using a virtual IP shared by active and standby routers, with hello messages every three seconds and priority-based failover.
Practical part four demonstrates hsrp with VLAN 10 and VLAN 20, configuring VLAN interfaces, trunks, root bridges, and static routes, with spanning-tree load balancing.
Build a multilayer network by configuring vlan 10 and 20, etherchannel, hsrp, ip routing, dhcp, and rip, with ip helper and icmp verification.
Learn how to create and manage a network infrastructure by mastering key switching and routing protocols, including DHCP, VLANs, inter-VLAN communication, Spanning Tree Protocol (STP), EtherChannel with Port Aggregation Protocol (PAgP) and Link Aggregation Control Protocol (LACP), and the Hot Standby Router Protocol (HSRP).
In this course, you'll start with the basics, understanding what a MAC address is and how it functions alongside IP addressing to facilitate network communication.
You'll dive into Virtual Local Area Networks (VLANs), which help segment networks for better performance and security, and explore inter-VLAN communication using Router on a Stick (ROAS), a technique that allows VLANs to communicate through a router.
The course also covers Spanning Tree Protocol (STP), an essential mechanism that prevents network loops and ensures redundant links remain available without causing broadcast storms.
You'll learn about Dynamic Host Configuration Protocol (DHCP), which automates IP address assignments, and how DHCP Relay helps extend DHCP services across different network segments.
EtherChannel technology is another key focus, providing a method to bundle multiple physical links into a single logical link for increased bandwidth and redundancy. You’ll gain insights into both PAgP and LACP, two popular EtherChannel protocols used for link aggregation.
Finally, the course covers Hot Standby Router Protocol (HSRP), which provides redundancy by allowing a backup router to take over in the event of failure, ensuring uninterrupted network connectivity.
By the end of this course, you'll have the skills to design and manage efficient, scalable, and resilient network infrastructures.
Theory is Cool, but Skills Are King, that`s why you will see in my course very detailed practice parts.
