Multiple IP Ranges - Single interface

[Amardeep Singh]

Hi

 

I need configuring multi ip ranges on single physical eth0 interface.

I am using ISC DHCPd version 3.1.2

Here is the scenario:

 

Relay-Agent-----(Gi)Cisco router(Fa)-----Layer 3 Switch-----DHCP SERVER

 

Relay Agent

ip address  192.168.0.130 255.255.255.128

 

Gi(cisco)

ip address 192.168.0.129   255.255.255.128

ip address 10.250.0.201  255.255.255.248 Secondary

ip address 10.250.0.209 255.255.255.240 Secondary

ip address 10.250.0.225 255.255.255.224 Secondary

ip helper-address 192.168.0.5

 

Fa(cisco)

ip address 192.168.0.1 255.255.255.224

 

Fa(switch)

ip address 192.168.0.2 255.255.255.224

 

eth0(Dhcp server)

ip address 192.168.0.5 255.255.255.224

GW 192.168.0.1

 

ISC dhcpd

Leases to offer from following:

192.168.0.128 /25

10.250.0.200 /29

10.250.0.208 /28

10.250.0.224 /27

 

Also Static hosts (MAC to IP) assignment, not automatic Ip.

 

So shall I make Share-network for each range or bind them together under
single shared-network.

It's a single physical network.
