So I have 2 core switches and 1 access switch, I have the vlans 1, 10, 20, 30 and 100. Vlan 10 is voip and what I would like to do is stop anyone on the other vlans from being able to see that subnet, but the phones get dhcp from a server on vlan 100. Vlan 100 is just servers so if it comes to it vlan 100 can access vlan 10.
My main gole it's to ensure that no one on the other vlans can see the phone network and the phones can still get dhcp. Currently for intervlan routing I am using ospf on a 2811 router with the network as 0.0.0.0
The ip ranges are as follows:
Vlan 1 - 10.1.1.0/24 -Mgmt Vlan 10 - 10.1.10.0/24 - VOIP Vlan 20 - 10.1.20.0/24 - PC's Vlan 30 - 10.1.30.0/24 - WiFi Vlan 100 - 10.1.100.0/24 - Servers
