DHCP Relay in BD with Multiple subnets

[shubhanshu_jaiswal]

I have a BD which has two subnets. The BD is mapped to Two EPGs each mapped to different subnets. I am configuring a DHCP relay that provides an IP Address from the primary subnet even if the host is connected to second EPG with a non-primary subnet vlan attached. How do you think I could solve it?

Hi, there is currently no solution, the DHCP relay IP address will always be set to the primary SVI IP address (primary subnet).

Yes...The DHCP relay IP address will always be set to the primary SVI IP address.
