Vlan config

Vlan 10

Domain Controller

File Server

DHCP Server

Users on Vlan 20 Subnet

If I was to implement this, would my users on Vlan 20 be able to communicate with the servers on Vlan 10 ?

What do I need to do ?

I already setup ip helper-address for DHCP to point to for Vlan 20.


Re: Vlan config

hi cisconoobie,,,

to make your user on VLAN 20 with the VLAN 10 servers you need to configure the intervlan routing which enable the communication between two vlan. you can configure it on you switch also but for that your switch must be a layer 3 switch or you have to use the router to configure the intervlan routing...

this link is having good configuration detail:

you can use this also:

hope this will help you

Re: Vlan config


Since the users and the servers are in different vlan you would need a layer-3 device to route traffic between the vlans.

IF u have a L3 device, you can configure the IP address for Interface VLAN 10 and 20 and you are good to go.

Re: Vlan config

Ok say I have a Layer 3 switch router and VTP is set to server and Vlan 10 and 20 are in it.

Will I be able to ping Vlan 10 computers from Vlan 20 computers ?

Doesnt this defeat the purpose of Vlans?

Is the point of Vlans ONLY to remove Broadcasts from other Vlans ? Is that the only purpose ?

Also, how can I check to make sure that Vlans are properly setup to communicate with eachother?

Re: Vlan config

see if you have layer 3 switch then you have to creat the SVI interface so that different vlan can communicate with each other...

if you not create the intervlan routing on switch also using the SVI, your different vlan willl not communicate with each other...

so configure your switch like this...

config)# ip routing

config)# interface vlan 10

config-if)# ip address ........

# no shut

config)# interface vlan 20

config-if)# ip address ........

# no shut

# end
