Adding another NIC interface / vLAN to Foreman

I have an existing Foreman 2.1.1 that works on vLAN 1 with its own separate DHCP server. I need to add PXE and kickstart service to another separate vLAN 2 that has a separate DHCP server. DNS service is shared by both vLANs.
How do I setup Foreman to support both vLANs?

You deploy another smart-proxy template with DHCP and PXE feature. Then you associate subnet and domain.

Foreman can manage DNS via one smart proxy and DHCP via the other one for a single host. That’s not a problem. You all define this.
