Cisco CCNA v2.0 200-301 : Full Course For Networking Basics

Configure two Cisco routers in Packet Tracer by setting hostnames Madrid and Miami, securing passwords with enable secret, enabling Telnet, assigning g0/0 IPs, testing with ping, and encrypting passwords.

Configure IPv6 addresses on gigabit interfaces, verify with show IP version six interface brief, and inspect CDP neighbors to identify directly connected devices Madrid and Miami.

Examine network topology architectures: the three-tier model (access, distribution, core) with fast routing and scalability, the collapsed core two-tier design, and the spine-leaf data center topology with top-of-rack switches.

Configure switch lab: set hostnames Madrid and Miami, enable ssh with domain name, RSA keys, and user credentials; assign management IPs on vlan and verify with show commands and CDP.

Perform a hands-on lab to configure switch ports, vlans, and port security across Madrid and Miami, including vlan 3–5 named phone, video, and wireless, with five mac addresses.

configure static routing by assigning ip addresses to gig zero zero, gig zero one, and gig zero two interfaces to ensure connectivity across four networks; verify with show ip route.

Configure inter-VLAN routing by creating VLANs 10, 20, and 30 on the switch, assign access ports, create a trunk, and set router subinterfaces to enable cross-VLAN communication.

Configure extended access control lists to block ftp, telnet, and http traffic from PC1 to PC2, apply the ACL inbound on router interface, and verify with show access-list.

Learn to configure spanning tree in rapid pvst, identify the root bridge, and force a non-root switch to become root by adjusting priority, using show spanning-tree.

Learn how hsrp interface tracking adjusts priority when a tracked interface fails. Explore hsrp object tracking, ip sla monitoring, and the basics of hsrp authentication, hello timers, and versions.

Follow three steps to configure hsrp on routers 1 and 2 with ip addresses 10.2 and 10.3, assign the pc gateway 10.1, and set router 1 to active.

Explore VRRP, the industry standard virtual router redundancy protocol for automatic router failover in IP networks, with versions 2 and 3, multi-vendor support, and configuration basics.

Learn Cisco’s GLBP, a router redundancy and load balancing protocol that uses multiple virtual MAC addresses and active virtual gateway and forwarder roles to share a single virtual IP.

Learn to configure an etherchannel between two switches using lacp, setting trunk mode, defining a channel group (switch 1 active, switch 2 passive), validating with show ether channel summary.

Delve into Cisco wireless architecture, comparing autonomous and lightweight access points, CAPWAP, and how a wireless LAN controller manages WLANs, security, and configuration.

Configure a single-area OSPF lab across four routers to provide connectivity for all PCs by advertising networks into area zero, and verify with show ip protocols and show ip route.

Practice ebgp configuration by setting up gigabit interfaces with ips, establishing bgp between customer and isp, advertising prefixes, and validating with show ip bgp summary and show ip bgp commands.

Explore password policies and alternatives to strengthen enterprise authentication by outlining online and offline attacks, dictionary and brute-force methods, and multi-factor solutions like MFA, certificates, and biometrics.

Explore next generation firewalls and integrated IPS, highlighting application visibility, deep packet inspection, SSL decryption, URL filtering, and signature or anomaly-based detection to secure networks.

Explore wireless security protocols, comparing WPA, WPA2, and WPA3, and learn how WPA3's forward secrecy and easy connect protect home and IoT networks.

Explore the control plane and data plane, defining how routing protocols and forwarding decisions guide packet paths, and how software defined networking centralizes control while distributing data plane across locations.

Explore controller-based networks that centrally manage 1000 devices with Cisco DNA Center and wireless controllers, covering design, policy, provision, and assurance, and automating AP configuration.

Learn how northbound and southbound APIs enable software-defined networks, with controllers translating application requests into device rules and maintaining network state.

Explore rest apis and how http requests transfer json data between clients and servers, using crud actions to read, create, update, or delete resources.

Explore configuration management with Ansible, Chef, Puppet, and Terraform for scalable network automation. Learn Ansible's agentless, push-based playbooks, Chef and Puppet agents, and Terraform's infrastructure-as-code with state and execution plans.

Explore dynamic routing protocols and how they auto-update routing tables to adapt to topology changes, versus static routing. Learn IGP and BGP choices for campus and internet edge.

Configure HSRP to protect the default gateway by using two routers as a single virtual router, enabling active and standby roles, virtual IP, and preemption.

Explore basic switching concepts by comparing hubs and switches, how switches use a MAC table to forward frames, and how broadcast domains and VLANs define network boundaries.

Configure dhcp snooping on switch by setting trusted trunk ports and dhcp server port, enable globally, and apply a limit rate of ten on the untrusted port with vlan ten.

Learn how OSPF route summarization improves scalability by reducing routing tables and LSAs. Explore virtual links, stub areas, NSSA, and default route propagation to optimize OSPF performance.

Master advanced OSPF configuration by redistributing static routes as type E1, configuring MD5 and clear text authentication, stub areas, and virtual links to ensure full adjacency and inter-area connectivity.

Configure basic BGP, covering IBGP and EBGP neighborship, loopback peering with update source, and EBGP multihop. Advertise routes using network and redistribution while verifying via show commands.

Master the CIA triad of confidentiality, integrity, and availability, and apply authentication, authorization, accounting, non-repudiation, least privilege, and defense in depth to protect data and systems.
