I Have two devices connected over two different physical interfaces and two different bridges. How can I add a route between them in the router, so that I will be able to ping device 2 from device 1 and vice versa. Please find the diagram below.

        Device 1                      Router                   Device 2
+-----------------+     +----------------------------+    +-----------------+
|                 |     |                            |    |                 |
|           eth1  |     | br2                    br1 |    |  wlan0          |
|   169.254.10.10 |-----| 169.254.50.1      10.0.0.1 |----| 169.254.168.11  |
| (self assigned) |     |                            |    | (self assigned) |
+-----------------+     +----------------------------+    +-----------------+

Can I achieve this using route tables?

Addresses in the 169.254.0.0/16 range are IPv4 link-local addresses, that is, addresses to be used only on the local network and not to be routed between network segments.

If you want to allow communication between Device 1 and Device 2 without having them on the same network segment, you should assign their network interfaces addresses from private internet address space, such as 10.0.0.1 assigned to interface br1 in your diagram.

  • Proxy arp may well work for what you need. I avoid 169.254.0.0/16 as much as I can. – user4556274 Oct 30 '17 at 19:21

  • He forgot to mention that he wants to route multicast in this setup (which won't work this way). Also, he's asking two questions about the same issue ... – dirkt Oct 30 '17 at 20:04
