Multiple VLAN -> IP Helper -> Microsoft DHCP
Posted: 27 Mar 2014 06:54
Hello friends,
first of all i would like to thank everyone for the help i already received in this forum. It is very very high appreciated!
I've got the following situation. I configured a switch with three different VLANs and connected a client to each port. On the switch there is also a IP Helper adress for each VLAN configured. It looks like this:
ip interface "VLAN50" address 10.0.50.1 mask 255.255.255.0 vlan 50 ifindex 2
ip interface "VLAN60" address 10.0.60.1 mask 255.255.255.0 vlan 60 ifindex 3
ip interface "VLAN70" address 10.0.70.1 mask 255.255.255.0 vlan 70 ifindex 4
vlan 50 enable name "VLAN 50"
vlan 50 port default 1/1
vlan 60 enable name "VLAN 60"
vlan 60 port default 1/2
vlan 70 enable name "VLAN 70"
vlan 70 port default 1/3
ip helper per-vlan only
ip helper address 172.16.43.1 vlan 50
ip helper address 172.16.43.1 vlan 60
ip helper address 172.16.43.1 vlan 70
In addition to that I have a WIndows Server 2k8 running as DHCP Server. I configured 3 DHCP scopes on the Server.
Now how can I tell the DHCP Server to use Scope 3 for VLAN 70, 60 for 2 and so on. Is the only possible way to assign the DHCP Server multiple addresses in the different vlans?
