thats right you need configure vlan with sub-interfaces for each subnet
dhcp doesn't cross subnets by default (it's broadcast). You can set up your vlans with a
helper address pointing to your dhcp server, ir you might try setting up a dhcp proxy. I
have never set up a dhcp proxy, but I use helper addresses all the time. Seems to work
ok.

Subject: Using a DHCP server for two subnets
Has anyone successfully used one DHCP to serve hosts on two subnets?
If anyone can share their dhcpd.conf syntax, I would appreciate. I think I have it correct because the DHCP server will issue:
dhcpd: DHCPDISCOVER………………………………..
dhcpd: DHCPOFFER……………………………………
dhcpd: DHCPREQUEST………………………………..
dhcpd: DHCPACK………………………………………..
But then I immediately receive:
in.tftpd[4254]: RRQ from 10.225.248.1 filename pxelinux.0
in.tftpd[4254]: tftpd: read: Connection refused
I am not sure if it is a dhcpd.conf configuration problem or not. My switch has “port fast” enabled. I can Kickstart servers with no problem but when I introduce a second subnet into my dhcpd, tftp fails.
How anyone ever seen this?
I had tried this a few months ago but was never able to get around it but I have a need to revisit this now and get it working.
Thanks.
