I am new to vlans and have a very old CCNA but have little experience.
We currently need two vlans, 500 systems ( call it vlan 500 ) and 200 systems ( call it vlan 200 ). All teh supporting servers ( DNS etc ) are on vlan 500.
I need to understand how to do the vlans across the layer 2 and layer 3 switches. ( by the way we have new dell switches ).
Vlan 200 is an isolated vlan and we do not want viruses or other problems to be able to pass to the vlan 500. We only want requests for DNS, DHCP, RDP, PXE, ICMP and Ghost to pass from vlan 200 to 500. We only want the replies for these services to go from Vlan 500 to Vlan 200.
Originally the plan was to implement the vlans in one layer 3 switch and the layer 2 switches and we hoped the layer 2 switches should be able to communicate with the one layer 3 switch.
After some discussion with a switch engineer at Dell, asked us to consider implementing the vlans on the layer 2 switches and also on the layer 3 switch. He stated talking about IP addressing and I do not know exactly what kind of ip scheme would make these work.
I selected ip address ranges
10.10.10.10 255.255.0.0 vlan 200
10.20.10.10 255.255.0.0 vlan 500
I need suggestions on a good layout of this network / vlan. We also need to understand more about access lists and the IP scheme to make it all work.
Thank you in advance
