Hi guys,
I'm testing the protocols rstp over logical-systems, but when I set the
priority over one interface for it work as root, it is not change the status
in the protocols rstp and the other interface don't change to Blocking.
theirs always keep on Forwarding state.
The topology that I am using it is the next:
SW1 (logical)-----------ge-3/0/2------------loop
fisico------------ge-3/0/3----------SW2(logical)
SW1 (logical)-----------ge-3/0/4------------loop
fisico------------ge-3/0/5----------SW2(logical)
I want to put the interface ge-3/0/2 as root interface.
These are configuration of both logical-systems:

I don't know, if my configuration is right? or maybe i have a mistake.
Somebody has tried to implement this feature on single chassis MX with
logical-systems??
Thanks in advance for your help.
