So in the picture you may see the structure of the network. Any advice is appreciated . What would be the best way to set up DHCP so that VLAN devices are getting IP if one of the L3 devices is down, at the moment i see only one option to supernet IP and divide in to half and create two DHCP’s with the same subnet mask and with different gateways. But I dont like that splitting as I will have to much of play with statically assigning IP’s those i don’t want to be changed.
Is where any other better way to achieve this.
Thanks in advance. 
Hey. You can practice with HSRP in Cisco Packet Tracer. And with VRRP in MikroTik world.
There is nothing to practice both vrrp and hasrp brings in to the same problem thats why i dont want to put dhcp on L3 switches
on cisco both vrrp and hsrp is supported.
What problem do you have with it?
You can use Bridges to mikrotik create vlan10 interface in ether1, and vlan10 interface in ether2 and put those 2 interfaces in same bridge, so dhcp server with be setup on bridge (same for other vlans), but should take care about PVST+ in switches to take care about loop!
