New Cisco CCNA (200-301) Volume 1: The Complete Course

Explore tcp/ip headers, focusing on source and destination ports and the well-known, registered, and ephemeral port ranges, and understand how this enables multiplexing for client–server applications.

Learn how routing moves packets across a network using layer 3 addresses and arp, and how routing tables combine connected and dynamic routes with rip, ospf, and bgp.

Configure DNS hostnames, set up static host tables, and point routers to a DNS server to resolve names to IP addresses, and learn FQDN and lookup concepts.

Access the switch CLI via console cable, telnet, SSH, USB, or browser; configure hostname, domain name, local user, and SSH crypto keys for secure lab access.

This lecture guides configuring a Cisco router with correct IP settings, DNS, and domain name, enabling passwords and SSH, generating RSA keys, and implementing radius-based triple-authentication with local fallbacks.

Learn to configure VLANs in a Cisco CCNA lab: create VLAN 10 and 20, set trunk and access ports, apply a BGP domain password, and verify inter-VLAN connectivity.

Learn to configure voice VLANs on Cisco switches by splitting a port into data and voice, using a dedicated voice VLAN and DHCP option 150 with call manager.

Explore private ip addressing versus public addresses, CIDR notation, and subnet masks, and understand class a, b, and c ranges, their increments, and the role of IPv4 routing.
