Homework Question

[jimM422]

Im pretty sure this is the right area to post my question. The question is "Q3: change the configuration to make all the computers communicate with each other.". Right now Im able to communicate between two computers that are on the same VLAN but Im not sure how I would make it so that all the computers can communicate with each other. Instead of a router we have a multilayer switch, if anyone could give me a basic idea of what to do that would be appreciated. 

Not sure if Im allowed to do a link but here's link to the pkt file on my github if you want a better idea of how it works: https://github.com/jmeegan2/Assignment-for-DataComm

@jimM422,

Welcome to the community!

Good job in providing details and the lab file. This allows for a more efficient response to an issue.

You need to configure interVLAN routing on Multilayer Switch 1 (3560-24PS). In your topology, enabling routing and creating the Switch Virtual Interfaces (SVIs) for each VLAN are the specific configurations that need to be completed.

Here is a link to a short article on how to accomplish this:
Inter VLAN Routing by Layer 3 Switch Difficulty Level : Basic

Hi JimM422 , 

For communication between  two different vlans , we will have to do inter Vlan routing on the MLS , this can be done by creating some SVI's on the MLS , Switch Virtual Interface ( SVI )  is  a logical interface on a multilayer switch that provides layer 3 processing for packets to all switch ports associated with that VLAN . 

On MLS , 

Create three SVI as there are three Vlans , 

(config )# int vlan 2 

ip add 192.168.20.1 255.255.255.0 ( The default gateway you specified on lan devices in VLAN 2 )

int vlan 3 

ip add 192.168.30.1 255.255.255.0  ( The default gateway you specified on lan devices in VLAN 3 )

int vlan 4

ip add 192.168.40.1 255.255.255.0 ( The default gateway you specified on lan devices in VLAN 4 )

Also By default a MLS doesn't maintain a routing table , so for it to run a routing table , we will run 

(config)# Ip routing 

Now , The ping would start working
