Forcing ports to transmit an MSTP BPDU
To force a port to transmit an MSTP BPDU, use a command such as the following at the Global
Configuration level.
TurboIron(config)#mstp force-migration-check ethernet 1
Syntax: [no] mstp force-migration-check ethernet
The variable specifies the port or ports from which you want to transmit an MSTP
BPDU.
Activating MSTP on a switch
MSTP scope must be enabled on the switch as described in “Configuring MSTP mode and scope”
on page 580 before MSTP can be enabled.
To enable MSTP on your switch, use the following at the Global Configuration level.
TurboIron(config)#mstp start
Syntax: [no] mstp start
The [no] option disables MSTP from operating on a switch.
Example
In Figure 93 four device routers are configured in two regions. There are four VLANs in four
instances in Region 2. Region 1 is in the CIST.
