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?

Yes, I disabled routing with no ip routing but its still not working.

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.

Thats not possible for me to share complete configuration.

If that is not possible then I do not know what else I can do to help you solve this issue.

Hello.
If someone can help about his problem about transparent bridging:
You have pc1 and pc2 both in same network, and one router between.
on router you bridge two interfaces
int f0/1 bridge group 1 no shut
int f0/0 bridge group 1 no shut
bridge 1 protocol ieee
and for bridging to work: NO IP ROUTING. otherwise, when you ping pc2 from pc1, arp won't pass to other link to pc2.
but
there is a case in wich bridging works with IP ROUTING:
in this case, ping between pc1 (1.1.1.10/24) and pc2 (1.1.1.11/24)works
packets on trunks are tagged with vlan 2
why router bridges in this case (when frame coming in R is tagged (and there is no subinterface on router for vlan2)) ?
Thanks

Hello
try the following on the rtr.
bridge irb
bridge 2 protocol ieee
bridge 2 route ip
int bvi 2
ip address 1.1.1.1 255.255.255.0
no shut
int fa0/0
no shut
bridge-group 2
int fa0/1
no shut
bridge-group 2
