Hi Tina

I am not sure I completely understand your question. Are you referring to a scenario where some of the members (e.g. RB1 ) are using some manual configuration and other is using the proposed method (e.g. RB2) in the CMT draft ?

PS: Both RB1 and RB2 are members of the virtual RBridge RBv

Hi,Tissa

Section 5.1 provides a simple general method to assign different trees to different members and it is easy to employ.
But in my opinion, it could be better to allow co-existence of default manner（cmt） and manual configuration
for distribution tree choosing，otherwise if some member RBs are manually configured and others are not configured at all,
compatibility problem with the current algorithm could occur.
So, maybe we should provide a unified tree distribution method which is compatible
with manual configuration and can ensure different member RBs obtain different  distribution tree?

Thanks,
Tina
