The following figure shows an example where there are two MST regions. Regions 1 and 2 have 2
spanning tree instances.

MSTIs in Different Regions
14.8.4 Common and Internal Spanning Tree (CIST)
A CIST represents the connectivity of the entire network and it is equivalent to a spanning tree in an STP/
RSTP. The CIST is the default MST instance (MSTID 0). Any VLANs that are not members of an MST instance
are members of the CIST. In an MSTP-enabled network, there is only one CIST that runs between MST
regions and single spanning tree devices. A network may contain multiple MST regions and other
network segments running RSTP.
