13.1.5 Multiple STP

Multiple Spanning Tree Protocol (IEEE 802.1s) is backward compatible with STP/

RSTP and addresses the limitations of existing spanning tree protocols (STP and

RSTP) in networks to include the following features:

• One Common and Inte rnal Spanning Tree (CIST) that represents the entire

network’s connectivity.

• Grouping of multiple bridges (or switching devices) into regions that appear as

one single bridge on the network.

• A VLAN can be mapped to a specific Multiple Spanning Tree Instance (MSTI).

MSTI allows multiple VLANs to use the same spanning tree.

• Load-balancing is possible as traffic from different VLANs can use distinct paths

in a region.

13.1.5.1 MSTP Network Example

The following figure shows a network example where two VLANs are configured on

the two switches. If the switches are using STP or RSTP, the link for VLAN 2 will be
