I am working towards my CCNA and i have a question about root bridge priorities. Several references have conflicting guidance on setting the root bridge priority. Everyone agrees that the default is 32768 and if all are at default, the lowest MAC wins. When you lower the priority, can you use any number between 1 and 32768, or doess it have to be in blocks of 4096 ( 0, 4096, 8092, 12288, etc)? All help is appreciated.
