Understanding Multiple Spanning Tree Protocol (802.1s) - Cisco

    https://www.cisco.com/c/en/us/support/docs/lan-switching/spanning-tree-protocol/24248-147.html
    Apr 17, 2007 · Multiple Spanning Tree (MST) is an IEEE standard inspired from the Cisco proprietary Multiple Instances Spanning Tree Protocol (MISTP) implementation. This document assumes that the reader is familiar with Rapid STP (RSTP) (802.1w), as MST heavily relies on this other IEEE standard. This table shows the support for MST in various Catalyst switches:

    https://www.cisco.com/en/US/docs/general/Test/dwerblo/broken_guide/spantree.html
    The MST region appears as a virtual switch to adjacent STP switches and MST regions. Figure 22-10 shows a network with three MST regions and an 802.1D switch (D). The CIST regional root for region 1 (A) is also the CIST root. The CIST regional root for region 2 (B) and the CIST regional root for region 3...

    Nov 16, 2007 · The Catalyst 4000, 6000, and 6500 series switches support Rapid Per-VLAN Spanning-Tree + (RPVST+) since CatOS Software Release 7.5. MST (802.1s) uses a modified version of RSTP (802.1w). This modified version is incorporated inside of MST and provides a fast convergence time in case of a failure in the network.

    Dec 13, 2006 · Backward Compatibility: MST is backward compatible with PVST+, Rapid-PVST+, and Prestandard MST (MISTP). MST switch is connected to the other STP (PVST+ and Rapid-PVST+) switches by the Common Spanning Tree (CST). Other STP (PVST+ and Rapid-PVST+) switches see the entire MST region as a single switch.

    Upgrade all switches to the latest software version. Ensure that the MST configuration on all switches match exactly. The name, revision, and instance VLAN mappings must be identical on all switches participating in MSTP. Configure all trunks on Cisco switches as 802.1Q (dot1q) trunks. Be sure to configure all edge ports.

    Dec 12, 2008 · VTP usability has been enhanced for Cisco ® Catalyst ® 6500 IOS implementations (12.2(33)SXI) to support spanning tree, or more precisely the MST instance, to the VLAN mapping table with IOS. The initial manual configuration via CLI or SNMP of a seed device results in an automatic update of dependent devices in the network.

Solved: MST with a PVST+ CST ROOT - Cisco Community
