Hi Nilesh, Sorry for don't put the release, I am working with JunOS 10.0R4.7 and the chassis is a MX960.
I was thinking the same about the bridge-id I noted it but I wasn't sure if it was possible to implement on logical-system with the same system MAC. Do you know if there are any limit with protocols of Layer2 and logical-systems? I will try with MSTP, I will comment the result of my tests.
