When i was studying STP (spanning tree) i got a doubt as to how switches break the tie to get elected as a root bridge when the bridge id is the same. It is by comparing the mac -addresses but how can one decide out of two mac-addresses which one is big to break the tie for root bridge election.
I hope i have asked it correctly.Can anyone elaborate on this.How to calculate this?
I agree with skylimit on how to detect the lower Bridge IDs.

Ties in the bridge ID cannot happen. The bridge ID is composed of both the bridge priority and the MAC address. The MAC address is designed by vendors in a way that NO two devices will have the same MAC address.
