The detailed configurations are as follows:z All devices on the network are in the same MST region.z Packets of VLAN 10, VLAN 20, VLAN 30, and VLAN 40 are forwarded along MSTI 1, MSTI 2, MSTI3, and MSTI 0 respectively.z Switch A and Switch B operate at the distribution layer; Switch C and Switch D operate at theaccess layer. VLAN 10 and VLAN 20 are terminated on the distribution layer devices, and VLAN 30is terminated on the access layer devices, so the root bridges of MSTI 1 and MSTI 2 are Switch Aand Switch B respectively, while the root bridge of MSTI 3 is Switch C.
