The other day I was delving a bit into spanning tree and I came across something that puzzled me.
Searching out which device was the root bridge I found the MAC address (BID) on the root bridge to be all zero's. (show spantree snippets). Spanning tree mode PVST+ Spanning tree type ieee Designated Root 00-00-00-00-00-00 Bridge ID MAC ADDR 00-00-00-00-00-00 Without finishing chapter 7 (Spanning Tree) in my LAN switching book I am puzzled as to whether this is a preset MAC address or self assigned. Any thoughts? Why or how did this occur?
