I see a VRRP configration on the Mikrotik wiki. https://wiki.mikrotik.com/wiki/Manual:VRRP-examples
But I don’t know on which router the DHCP server should be configured or should it be on a separate router and should it be connected to the switch?

Nowbody knows?
VRRP uses like netwatch up/down scripts own scripts know as “on-backup and on-master”.
DHCP should be enabled at “on-master” but disabled when “on-backup”.
DHCP Leases can be exported and imported via shared disk storage via separate scripts.
The VRRP backup router will not answer ARP requests. It is not documented if the DHCP server on the backup VRRP will answer on DHCP requests.when VRRP is used.(Does the DHCP server use the VRRP assigned MAC or not?)
Problem is the lease table , not being synced between master and backup. Some try to do it by scripts: http://forum.mikrotik.com/t/ask-multi-dhcp-servers-for-failover-purpose/62529/1
In a large organisation the DHCP server is separate from the router function. The redundancy is created by using other parts of the divided address pool. Static DHCP adresses should be added to both master and backup, and will not conflict. Depending on which DHCP server is answering the IP address will be different. (Unless RADIUS is defining the IP address ??? Never tried.). The DHCP servers are connected to different subnets in different parts of the LAN infrastructure to guarantee availability (Cisco helper addresses may be needed to carry the requests and responses over Cisco routers)
Thanks for the response, I will try it out and let you know if it worked.
