Routing public /29s from routers to firewalls

I’m still a bit of noob when it comes to routes. I understand what they are and what they do but not necessarily how to configure them. I could really use some help on how to configure a couple of routes on two Cisco routers. Currently we have two Cisco routers and two Cisco Meraki firewalls. We get two /30s and two /29s from our ISP. This is the configuration we’d like to have: https://i.imgur.com/17BJNFZ.png *

*The Cisco Routers are router1 and router2. The Meraki Firewalls are fw1 and fw2.

We’re planning on setting up both MX100s in a Warm Spare Configuration. Our ISP doesn’t allow the use of a /29 as a the public-facing IP address for any router. They only allow a /30. So, from the two Cisco routers, we need to route two /29s (one from each router) to each to the two Meraki Firewalls. I could use some help on figuring out how the routes will be configured.

Just FYI, we have two separate lines from our ISP, so we still get all the correct routes.
