How to split routes between 2 ISPs in Mikrotik?

Question

Mikrotik

There is Mikrotik hexLite, which, conditionally:

• LAN1 is connected to a micro-office network of ten PCs with static IP
  
• ISP 1 is connected to LAN2 (provider gives settings via DHCP)
  
• ISP 2 is connected to LAN 3 (provider gives settings via DHCP)
  

It is necessary that requests to certain external addresses go through ISP1, and to the rest - through ISP2.

Answer 1

Mark traffic in the mangle and send it to the desired route.

Answer 2

In the rules of the "mangle" firewall table, on the "action" tab, there is a "route" option. When using it, traffic under the specified conditions will be sent to the router you specified there.
ps It is not necessary to mark traffic at the same time!
