Cisco CCNA Packet Tracer Ultimate labs: ICND2 Exam prep labs

Learn to download, install, and configure Cisco Packet Tracer, including Windows and Linux versions, set up a basic two-router topology with IP addressing, and login steps.

Learn how to download and install Cisco Packet Tracer on a Mac. Register for the Cisco Networking Academy and build a basic router–switch topology, configure interfaces, and save your work.

Practice router-on-a-stick inter-VLAN routing between VLAN 10 (10.1.10.0/24) and VLAN 20 (10.1.20.0/24), assign last IPs, configure the switch, and verify PC connectivity via ping.

Configure a router-on-a-stick by creating VLAN subinterfaces for 1, 10, and 20 with dot1q encapsulation and a native VLAN 1, and assign 10.1.x.x/24 addresses.

Configure a campus network with a layer-3 core switch, inter-VLAN routing for VLANs 10, 20, 30 and 100 (server), with trunk links between switches and access ports for the PCs.

Configure a multilayer switch with VLANs 10, 20, 30, and 100, set access and trunk ports, enable IP routing, and create SVIs for inter-VLAN routing.

Configure vlan 10 on the access switch and trunk the uplink with dot1q. Use an svi ip and a default gateway, and enable vtp to distribute vlans.

Configure vlans and trunk ports on campus switches, set vtp client mode to learn domains, and verify domain learning and connectivity with ping tests across switches and PCs.

Configure a VTP domain Kenay to manage VLANs across switches; ensure VLANs are added on switch one and switch two but do not synchronize with switch three, and verify replication.

Configure VTP domains and set switch one as server, switch three as client, and switch two as transparent to control VLAN propagation; verify trunks and VTP status, and save.

Troubleshoot VTP and VLAN trunking to synchronize VLAN databases across switches when VLANs are added to switch one, using show VIP status and other commands to diagnose.

Demonstrates troubleshooting VTP domain mismatches and trunking problems across switches, showing how to synchronize VLAN databases and verify VTP status and domain configuration.

Investigate disabling spanning tree on two layer two switches and how a pc1 to pc2 icmp ping may traverse, with ports blocking, in packet tracer simulation mode.

Disabling spanning tree on layer 2 switches causes broadcast floods and mac address table instability, risking network meltdown; re-enabling spanning tree restores learning and forwarding and prevents floods.

Explore a campus network topology in Packet Tracer with two core switches, three access switches, VLANs 10/20/40 and 100, trunking, inter-VLAN routing, spanning tree, NAT, IGP, and HSP.

Power on core and access switches, add power supplies, and boot devices; manually configure hostnames, shut unused interfaces with range commands, and save configurations.

Configure campus routers and switches by enabling interfaces, verifying with show ip interface brief, and shutting unused ports to improve security; automate with scripts and save configurations for exams.

Learn to configure enable and secret passwords, set up VTI lines with login and password on campus switches, and copy commands across devices with manual checks and saving config.

Set the vtp mode to transparent and the vtp domain to CCNY, then create vlan 10, 20, 30, and 100 across campus switches, and verify with show commands.

Configure access and trunk ports on campus switches using switchport mode, trunk encapsulation, VLAN assignments, verify with show commands, disable DTP on access ports, and save configurations.

Explore campus network labs in Packet Tracer by configuring discovery protocols and verifying spanning-tree links. Optimize traffic with core switches as roots, implement etherchannel, and verify routing and connectivity.

Learn to verify and troubleshoot layer 2 adjacencies using CDP and LLDP, enable CDP on all devices, and interpret neighbor outputs across multi-vendor networks.

Compare CDPR and LDP in campus networks, showing how to enable LDP on Sasko devices and read show commands to interpret CDPR and LDP neighbor outputs.

Optimize the Packet Tracer campus network with spanning tree to reduce blocking and balance uplinks across VLANs. Learn to use show spanning-tree, set root and backup routes, and improve throughput.

Bond core switch links with an ether channel to optimize VLAN and server traffic. Configure port channel on both sides and verify with show outputs using LCP or PGP.

configure the port channel as the shared spanning-tree link between switches, mirror configuration on both the port channel and physical interfaces, and set the spanning-tree type to point-to-point.

Configure layer 3 on switches by enabling ip routing, creating SVIs, and assigning IP addresses to VLANs to enable inter-vlan routing, then verify with show commands.

Configure ip addresses on the access switches and vlan 1 ip, verify connectivity with ping, enable ip routing and a default gateway, then save configurations.

Configure default gateways, set IP addresses, and verify that packet tracer network components—switches, server, and PCs—can ping each other, using hot standby protocol on the switches and router.

Configure hsp on the core switches to create a virtual default gateway with a virtual ip address for vlan 10 and 20, using standby and preemption for resiliency.

Configure HSRP on VLAN 10, 20, and 30 with virtual IP addresses, set device priorities and preemption, and verify connectivity across the network.

Configure HSRP on campus switches with standby IP and preemption, verify active and standby roles, and test default gateways on VLAN 1 and PCs for server reachability.

Configure a campus network in packet tracer using EIGRP with autonomous system 100, no auto-summary, multiple interface neighbors, advertise loopback networks, verify with show ip route and PC ping.
