mutli vlan environment

guys,

 

i am playing with packettracer to get more familiair with specific items.

i create a small environment with different vlans . They all have their own subnet. There is one routervlan.jpg

if i understood the theorie correct, i link vlans to specific ports. But how can these different computers communicate with each other and how can the get to the Internet? Also, i think i need to give the router multiple ip-addresses, one for each subnet to act als a gateway.
Am i correct?

Last question, something completely different, there is no 48 port switch in Packettracer, am i correct?

 

Hope someone can help.

thanks.

Re: mutli vlan environment

Hello

The routers lan facing interface will have the L3 sub-interface addressing for the multiple vlans for your network.

rtr

interface x/x
description lan facing
interface x/x.10
description vlan 10
encapsulation dot1q 10
ip address 10.10.10.x 255.255.255.0

interface x/x.20
description vlan 20
encapsulation dot1q 10
ip address 20.20.20.x 255.255.255.0
etc..


 

On the switch2, its connection attaching to the router will be a trunk interface and it will also have all the l2 vlans relating to the rtrs l3 subinterfaces, as will switch 3

switch2
interface x/x
description link to rtr
switchport mode trunk

interface x/x
description link to switch3
switchport mode trunk\

 

vlan 10
vlan 20

vlan xx
etc..

 

switch3
interface x/x
description link to sw2
switchport mode trunk

 

vlan 10
vlan 20

vlan xx
etc..



kind regards
Paul

Re: mutli vlan environment

Many thank for the reply. But the connection from switch to switch will also be a trunk connection?

That is correct. All the connections between switches should be trunk.

Re: mutli vlan environment

And what if i connect the switches from the backsite instead of using a rj45 cable, is that also possible and can i use the same commands?

Re: mutli vlan environment

I am not familiar with packet tracer and not sure what you mean by "backsite" but you want to use Ethernet ports to connect the switches together.

I apologize for the misunderstanding. What i meant was real iron, real cisco devices, not PT this time.
