[Bridge] Enquiry on Linux bridge

[-- Attachment #1.1: Type: text/plain, Size: 2818 bytes --]

Dear all,

I'm currently working on a Ethernet bridge for a system. I have a machine(not PC, but an embedded system) which has two Ethernet ports, I wanted to configure it into a Ethernet bridge which connect other PC.

I have tested on configuring it into a bridge where the two PC able to ping each other and send files. I'm wondering that whether I can involve the embedded Linux system in the network, where the two PC able to detect the Linux OS( embedded system) and able to send files and communicate with it as the figure below:

[cid:image006.png@01CB1861.C5C49440][cid:image007.png@01CB1861.C5C49440]                                                                                                     [cid:image007.png@01CB1861.C5C49440]


PC1


PC2




PC1


PC2





I have try to add an IP to the bridge (virtual port) and the PCs are able to Ping the bridge's IP.

Then I'd tried to configure the network to be like below:
[cid:image011.png@01CB1861.C5C49440][cid:image012.png@01CB1861.C5C49440][cid:image007.png@01CB1861.C5C49440]                                                                                                                                              [cid:image007.png@01CB1861.C5C49440]


PC1 and PC2 can ping each other can communicate well. I have added IP to both bridge, but the result is that, PC1 only able to ping bridge1's IP and not bridge2's IP. PC2 as well, is only able to ping bridge2's IP and not able to ping bridge1's IP.

Do you have any suggestion for me to configure the bridge so that both bridge can be detected by each of the PC that connected to them?

Thank you very much in advance.

Regards,
Ming Ann

 As far as I can tell, the setup you describe should work as expected. I am not sure what causes the problem you describe. The first thing I would check is if the bridge interfaces (br0) have the same MAC address, they should not.
