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.
Best regards,
