We could give you better answers if you would supply more detail about what you have put into your configuration. But assuming that you really do want to do transparent bridging (and not something like Integrated Routing and Bridging) then I have these suggestions for you.
- configure a bridge group.
- assign the bridge group to the Ethernet interfaces of both routers and to the E1 interfaces of both routers.
- turn off ip routing (no ip routing - this is the step that most people miss in trying to do this).
Thanks for replying. I already configure bridge group and assign to E1 Port and Gigabit Ethernet port also. But still not working.
Your response tells us that you have configured the bridge group and assigned it to the interfaces. But it does not tell us whether you have disabled ip routing as I suggested. Have you done the no ip routing?
Thanks for clarifying that you did disable ip routing. Perhaps if you post the complete configuration we might find the reason why it is not working.
Why do you post the configuration and change the addressing to private
then we mabye assist in solving your problem.
