Mangle with address list

I have 3 outgoing connections. They are connected to a RB1100. I want to be able to send a specific IP address over a specific outgoing interface by creating a address list and then filling in the IP addresses.

How do I create this? I have added a default gateway for the new connection with a specified routing mark. I am unsure of how to setup the mangle rules in order to accommodate for the feature I require. Any advise?

Two ways to do this.

  1. (I would not use this method)
    a Use Mangle with action add to address list
    b Setup the routing mark for that address list

  2. (I would use this method)
    a Use mangle to mark an address range with routing mark
    b Remove that address range from the DHCP pool
    c Add static address assignments for those reserved addresses
