Hi, I need little bit help out here.

Cisco config:

spanning-tree mst configuration
 name Region1
 revision 3
 instance 1 vlan 2-10
 instance 2 vlan 10-20
 instance 3 vlan  20-30
!

Extreme config? How to map vlans in each instance?   #configure stpd
mst1 add vlan Vlan_10 ports ?? why it should be associated with physical
ports?

configure mstp region Region1
configure mstp revision 3
configure mstp format 0
create stpd mst0
configure stpd mst0 mode mstp cist
configure stpd mst0 forwarddelay 15
configure stpd mst0 hellotime 2
configure stpd mst0 maxage 20
configure stpd mst0 max-hop-count 20
configure stpd mst0 priority 28672
configure stpd mst0 default-encapsulation dot1d
create stpd mst1
configure stpd mst1 mode mstp msti 1
configure stpd mst1 max-hop-count 20
configure stpd mst1 priority 28672
configure stpd mst1 default-encapsulation dot1d
create stpd mst2
configure stpd mst2 mode mstp msti 2
configure stpd mst2 max-hop-count 20
configure stpd mst2 priority 28672
configure stpd mst2 default-encapsulation dot1d
create stpd mst3
configure stpd mst3 mode mstp msti 3
configure stpd mst3 max-hop-count 20
configure stpd mst3 priority 28672
configure stpd mst3 default-encapsulation dot1d
configure stpd s0 mode dot1d
configure stpd s0 forwarddelay 15
configure stpd s0 hellotime 2
configure stpd s0 maxage 20
configure stpd s0 priority 32768
disable stpd s0 rapid-root-failover
configure stpd s0 default-encapsulation dot1d
enable stpd s0 auto-bind vlan Default
