Implementing MSTP on a Bridged Network

The following procedure is recommended for configuring MSTP on a network. Beginning with a set of MSTP-
capable Ethernet bridges, do the following for each bridge on the network:
NOTE
Careful network analysis and planning should inform each step of creating an MSTP network.
NOTE
MSTP does not need to be enabled to map a VLAN to an MSTI. However, the mapping must be
identical for each bridge that belongs to the MSTP region.
1. Disable STP. For more information, refer to
2. Configure one or more Multiple Spanning Tree Instances (MSTI), each with a unique bridge priority. For more
information, refer to
3. Create static VLANs and map them to the MSTIs. For more information, refer to
Static VLAN".
4. Configure individual MSTI for each switched Ethernet port and/or Ethernet trunk interface that will transmit/
receive MST BPDU (Bridge Protocol Data Unit) traffic. For more information, refer to
"Managing Multiple Spanning Tree Instances
5. Set the STP protocol version to MSTP, configure the MST region identifier and revision level, and then
enable STP. For more information, refer to
Section 5.36.4

Configuring STP Globally

To configure global settings for the Spanning Tree Protocol (STP), do the following:
1. Make sure the CLI is in Configuration mode.
Navigate to switch » spanning-tree.
2.
3. Configure the basic STP settings by configuring the following parameter(s):
Parameter

version { version }
hello-time { hello-time }

Description
Synopsis: true or false
Default: true
Enables STP/RSTP/MSTP for the bridge globally. Note that STP/
RSTP/MSTP is enabled on a port when it is enabled globally and
along with enabling per port setting.
Synopsis: { stp, rstp, mstp }
Default: rstp
The version (either only STP or Rapid STP or Multiple STP) of
the Spanning Tree Protocol (STP) to support.
Synopsis: An integer between 1 and 10
Default: 2
The time between configuration messages issued by the root
bridge. Shorter hello times result in faster detection of topology
