Develop subnetting skills for the CCNA exam with a hands-on lab that divides 192.168.1.0/24 into two subnets, configures router and switches, assigns IPs, and tests connectivity with ping.

This lab guides you through subnetting a /24 into two /25 networks, calculating 192.168.10.0/25 and 192.168.11.0/25, and identifying first and last hosts and broadcasts.

Configure a two-interface router with 192.168.1.126/25 and 192.168.1.254/25, assign PCs 192.168.1.1 and 192.168.1.129 with gateways 192.168.1.126 and 192.168.1.254, and verify connectivity using ping and ARP/ICMP.

Configure the switches' switched virtual interfaces with the correct IP addresses, verify host and router reachability via ping, and set default gateways to ensure full network connectivity.

Practice subnetting in a packet tracer lab by dividing a given network into three subnets, assigning first IPs to PCs, last IPs to routers, and configuring default gateways and connectivity.

Subnet 192.168.1.0/24 into three /26 subnets by stealing two host bits, yielding subnets such as 192.168.1.0/26, 192.168.1.64/26, and 192.168.1.128/26, then configure the devices in the topology.

Explore subnetting lab 2 from CCNA 200-301 labs by calculating first and last hosts and broadcasts, then configuring routers, switches, and PCs and validating connectivity.

Explore how subnet masks determine if two devices are in the same subnet, and practice verifying connectivity with ping, router interfaces, and routing tables in Packet Tracer.

Explore subnetting in a ccna lab by determining if two routers share a subnet using ip addresses and masks, validating with ping, arp, and icmp in packet tracer.

Configure a router as a dhcp server to allocate ip addresses from a pool to pc0, excluding addresses, using the router as default gateway and dns, and verify loopback connectivity.

Configure a dhcp server on the router by creating a dhcp pool, excluding addresses, and setting network, default gateway, and dns server; verify allocations with ipconfig and show dhcp binding.

Explore dhcp server lab 1 by enabling dhcp, observing the dhcp messages—discover, offer, request, acknowledge—and assigning ip addresses to PCs via router broadcasting in packet tracer simulation.

Configure dhcp pools for vlan ten and vlan 20 on the router to allocate ip addresses to devices, enable inter-VLAN routing via the switch, and ensure dhcp forwarding.

Configure dhcp server labs by excluding first ten addresses from each subnet, creating vlan ten and vlan 20 pools, enabling routing and dhcp forwarding with ip helper, and verifying bindings.

Observe DHCP flow in Packet Tracer simulation: a broadcast from the client, relayed by the switch to the router, with the server allocating an IP to the client.

Learn to configure a router on a stick for inter vlan routing between vlan 10 and vlan 20, using a layer switch for management and encapsulation on the router link.

Master router-on-a-stick inter-vlan routing by configuring router subinterfaces with dot1Q encapsulation for VLANs 1, 10, and 20, including the native VLAN, and verify connectivity across PCs and switch.
