As shown in Figure 1-2:
Map VLANs 1 through 10, VLANs 11 through 20, and VLANs 21 through 30 to MSTI 0, MSTI 1,
and MSTI 2 respectively.
Traffic of VLANs 1 through 30 on Device C and Device D are dually uplinked to Device A.
Configure Smart Link on the devices for dual uplink backup, using VLAN 1 (the default) for flush
