The CIST Root Bridge & Backup CIST Root Bridge
In order to configure a switch to be the CIST Root Bridge of a Spanning Tree network, you
just have to make sure that the Bridge Priority (which is the most significant 4 bits of the
Bridge ID) of the switch is the lowest among any of the switches on the network. Similarly for
the Backup CIST Root Bridge, it must have the next lowest Bridge Priority of all the switches.
This Bridge ID is a concatenation of 3 values: a 4 bit Bridge Priority (most significant), a 12
bit System ID (less significant), and the 48 bit MAC address of the local switch (least
significant) (see
).
