download and install the latest Cisco Packet Tracer, explore a basic topology with routers, configure IP addresses, test connectivity, and save configurations to prepare for ICND1 labs.

Download and install Cisco Packet Tracer on a Mac, register for a free Cisco Networking Academy course, and build a basic topology with routers, switches, and end devices.

Power on the devices, configure hostnames and IP addresses as shown, set the enable password and enable secret, configure the first five vty lines, and test telnet and console access.

Power on devices, bypass the initial configuration dialogue, set hostnames, configure ip addresses on interfaces, enable and verify connectivity, and secure access with enable and secret passwords.

Configure vty lines 0-4 with a password for telnet access, set a console password, and apply an enable secret; save the configuration with copy running-config startup-config.

Explore the life of a packet from source to destination as you analyze mac addresses, encapsulation, and ICMP echo requests in a packet tracer simulation.

Trace the life of an icmp echo in a ccent packet tracer lab, identifying destination mac addresses and encapsulation (ethernet ii vs hdlc) at each network point.

Develop four ipv4 subnets from 192.168.1.0/24, configure routers, switches, and dhcp servers, and validate client access to Cisco dot com and Facebook dot com via a dns server.

Subnet a 192.168.1.0/24 into four /26 subnets (192.168.1.0/26, 192.168.1.64/26, 192.168.1.128/26, 192.168.1.192/26) and plan site and link networks plus dhcp server configuration.

Configure and verify a 192.168.1.0/26 subnet by calculating network, broadcast, and host addresses; assign router, switch, and dhcp server IPs, set default gateway and dns, and test connectivity.

Demonstrates subnetting with subnet addresses, first hosts, and broadcasts; configures serial interfaces and IP addresses; verifies connectivity to DNS, sasko.com, and facebook.com via ping and trace.

Configure subnets, assign router and switch IPs, set the DNS server and gateway, enable DHCP, and verify cross-subnet connectivity through ping tests and internet access.

Subnet the 192.168.1.0/24 into eight-host subnets, extend to 192.168.164.0/26 for site three, allocate /30s for three serial links, configure static IPs, and verify access to Cisco.com and Facebook.

Subnet a 192.168.1.0/24 into four /26 subnets, then further divide one /26 into /28s for eight-host subnets, and create /30 links for point-to-point connections.

Master subnetting lab techniques by configuring interfaces, calculating first/last hosts and broadcast addresses, and testing IP connectivity from PCs to the internet using DNS, ping, and default gateways.

Configure a dhcp server for the 10.1.0.0/24 network with an excluded range 10.1.1.0–10.1.100, name the pool PC, set gateway 10.1.0.1, and verify PC0 acquires IP and pings router loopback.

Configure a dhcp server on the router with an exclusion range and 10.1.1.0/24 pool, gateway and dns. Verify by a pc obtaining an ip and pinging the router.

Configure DHCP on the router to create VLAN 10 and VLAN 20 pools (10.1.0.0/24 and 10.1.20.0/24), excluding first 10 IPs; gateway to switch one and DNS to R1; verify reachability.

Configure DHCP on the router for VLAN 10 and VLAN 20, create excluded ranges, and set up DHCP pools with 10.1.x.x networks, using the switch as default gateway.

Configure DHCP on the switch to forward requests to the router for VLAN 10 and VLAN 20, enable IP routing, and set static routes to ensure device reachability.

Use a router on a stick to enable inter-vlan routing between vlan 10 and 20. Configure the subnets and switch management address, and verify ping between PCs and the router.

Configure router on a stick by creating subinterfaces for VLANs 1, 10, and 20 with dot1q encapsulation and 10.1.x.0/24 IPs; set the switch as a trunk and verify inter-vlan connectivity.

Engage in a practical CCENT ICND1 prep quiz using Packet Tracer, download and trace a packet to prove answers about ping, ICMP, MAC address table, and broadcast and collision domains.

Observe arp broadcast and mac learning in packet tracer as icmp traffic from pc1 to pc4 triggers an arp request; a hub floods frames and non destined packets are dropped.

Explore how broadcast and collision domains behave in hub-based networks, highlighting flooding, MAC address learning, and why switches provide multiple collision domains.

Explore how switches use mac address tables to flood broadcasts and isolate collision domains, using op packets and ICMP ping to show how data flows in networks.
