I have tested my bridge in GNS3 and it works fine.

Why my bridge works in GNS3?

And why it does not work in EVE-NG?

What I am doing wrong?

Can anybody give me to test L2 image that exactly work in EVE-NG with this bridge?

The problem was with L2 image.

I have change it to the correct L2 image and all started to work good.

Thanks to Uldis (UD, UD-EVE in live chat)! He helped me to solve the problem.
