routes - SDN Faucet multi-subnet routing configuration

Question

I am trying to setup Faucet to manage a set of subnets. Here is the schema: Basically I have 2 Linux machines with network interfaces in two subnets running Open vSwitch that should act as routers. The idea would be to have anyone from each subnet should be able to ping anyone in any other subnet.

I am able to route the traffic between A and B quite easily, however whenever I try to create rules that allow to route between B and C I cannot make it work. I think might not work because I placed two DPs on the same subnet but only one is a machine with the IP set as “faucet_vips”. On top of that I would also like to tell to AB that whenever an host from A wants to talk with someone in C it should forward the traffic towards BC

Can someone tell me where I am making a mistake or at least suggest me how to debug this?

Here follows my configuration file:

vlans:
    A:
        vid: 11
        faucet_vips: ["192.168.0.254/24"]  
        faucet_mac: "00:00:00:00:00:11"
    B:
        vid: 12
        faucet_vips: ["192.168.1.1/24"]  
        faucet_mac: "00:00:00:00:00:22"
    C:
        vid: 13
        faucet_vips: ["192.168.2.1/24"]  
        faucet_mac: "00:00:00:00:00:33"

dps:
    br0:
        dp_id: 0x1
        hardware: "Open vSwitch"
        interfaces:
            1:
                name: "vlan11_if"
                native_vlan: A
            2:
                name: "vlan12_left"
                native_vlan: B
    br1:
        dp_id: 0x2
        hardware: "Open vSwitch"
        interfaces:
            1:
                name: "vlan12_right"
                native_vlan: B
            2:
                name: "vlan13_if"
                native_vlan: C

routers:
    router-1:                           
        vlans: [A, B]      
    router-2:                           
        vlans: [B, C]
