Multiple smart link groups load sharing configuration example
Network requirements
As shown in Figure 25:
 Device C is a smart link device, and Device A, Device B, and Device D are associated devices.
Traffic of VLANs 1 through 200 on Device C are dually uplinked to Device A by Device B and
Device D.
 Implement dual uplink backup and load sharing on Device C:
 Traffic of VLANs 1 through 100 is uplinked to Device A by Device B.
 Traffic of VLANs 101 through 200 is uplinked to Device A by Device D.

Configuration procedure
1. Configure Device C.
# Create VLAN 1 through VLAN 200. Map VLANs 1 through 100 to MSTI 1. Map VLANs 101 through
200 to MSTI 2, and activate MST region configuration.

# Shut down ports GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2, disable STP on them, and
configure them as trunk ports that permit VLANs 1 through 200.
