Configuration

Packet tracer 8.1.1, using the starter file provided

Summary

Using the table I created beforehand, I assigned IPs to the endpoint devices and connected them to their switches. I then set up the VLANs on the switches (had to redo it a few times because I assigned the wrong numbers), and successfully pinged between devices on the same VLAN (within the switches), while not pinging between the different VLANs. After this, I configured and connected all trunk ports, and set up routing. From there, I was still able to ping within all the VLAN networks across the switches, but I have not been able to ping between the different VLANs. Strangely enough, when I examined it in simulation mode, the packet reached the target successfully, but failed to return to the original sender.

Commands

(config)interface range FastEthernet 0/x-y (let's you configure multiple ports at one time)

(config-if-range)switchport access vlan x (defines the vlan for all ports in the range)

(config)ip routing (turns on routing on multilayer switches)

(config)interface vlan 100 (brings you into vlan interface config mode)

(config-if)ip address 10.25.100.1 255.255.255.0 (set the ip address of 10.25.100.1 for vlan 100 on a routing switch)

NOTE: This only needs to be set on the router-switch acting as the gateway for the vlan
