Configure the switch to add VLAN tag 103 and 104 to packets from the internal 
networks and VLAN tag 105 and 106 to packets from the external networks and to 
send packets from all of these networks to the FortiSwitch-5003A board.

Add spanning tree instance 3 for packets from the internal networks. Add VLAN 
tags 103 and 104 to this spanning tree instance. Set the priority of this spanning 
tree instance to 5.

spanning-tree instance 3 vlan 103 104
spanning-tree instance 3 priority 5

Add spanning tree instance 5 for packets from the external networks. Add VLAN 
tags 105 and 106 to this spanning tree instance. Set the priority of this spanning 
tree instance to 5, the same as instance 3.

The FortiSwitch-5003A board in slot 1 requires the following configuration 
settings:

Disable communication between the FortiSwitch-5003A boards:

config switch fabric-channel physical-port

edit slot-2/1

set status down

end

Create an MSTP configuration that includes the same name and revision as was 
added to the external switch. For example, if the name is tree_1 and the revision 

is 1:

config switch fabric-channel stp settings

set name "tree_1"
set revision 1

end
