Two Root bridges in a single Ring network

[n-learner]

Hi,

I am running MST in my ring network where two switches showing as root for the same instances...... What could be the reason for two switches being a root???

But it is working fine without any probs???

Check the Trunk line and verify the VTP messages are transferring through link.

no chances of occurring like . in MSTP cannot be TWO root bridge for same instance.
