Configuration procedure
1. Configure Device A.
# Create VLANs 10 and 20, map VLAN 10 to MSTI 1 and VLAN 20 to MSTI 2, and activate MST region
configuration.

# Disable physical state change suppression and STP on GigabitEthernet 1/0/1 and GigabitEthernet
1/0/2, and configure the two ports to trust the 802.1p precedence of the received packets. Configure the
two ports as trunk ports, remove them from VLAN 1, and assign them to VLAN 10 and VLAN 20.
