          - 0.0.0.0/0 100.127.2.6 table=200
          - 100.127.2.0/29 100.127.2.2 table=200
      - conn_name: dummy0
        type: dummy

            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
