I have one Windows server 2012R2 which has IP address & I also have Cisco Catalyst 2960-X Series which is layer 2, we managed to do inter VLAN routing by updating its firmware, where we got limited routing feature. Now we have made 5 VLANs in it so how do I get automatically IP addresses from my DHCP server for particular VLANs?

    Use IP helper address on your layer 3 VLAN. Command is: ip helper-address <DHCP Server IP> – user36472 Nov 12 '18 at 7:40
  • The switch acts as a dhcp-relay agent. It adds a field to the request so the dhcp server knows which network originated the request. – Ricky Beam Nov 12 '18 at 20:27
  • Hi Rahul -- I take it the Windows server is the DHCP server? – jonathanjo Nov 13 '18 at 15:05

You need to use DHCP helper address in your middle routers or switches between your dhcp server and your vlan nodes

Take a look of this link: https://www.cisco.com/en/US/docs/ios/12_4t/ip_addr/configuration/guide/htdhcpre.html

Hope this helps. Regards
