Example for simple policy base routing with Network Manager:

    network:
      network_manager:
        iface:
          - conn_name: 'System eth1'
            routes4:
              - 0.0.0.0/0 192.168.78.1 table=400
            routing_rules4:
              - priority 10 from {{ ansible_eth1.ipv4.address }} table 400
              - priority 10 from 192.168.78.251 table 400

Example with network-scripts: 

    network:
      network_scripts:
        iface:
          - name: ens256
            ip:
              - ipaddr: "100.127.2.2"
                prefix: "29"
          - name: lo
            type: loopback
            ip:
              - ipaddr: "18.12.3.1"
                prefix: "32"
            route:
              - default table 200 via 100.127.2.6
              - 100.127.2.0/29 table 200 via 100.127.2.2
            rule:
              - from 18.12.3.1 table 200
        pbr:
          table:
