2) Configuration on Device B
# Configure the suppression time of physical-link-state changes on GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2 as zero, disable STP, configure the two ports as trunk ports, and assign them to
all VLANs, and configure them to trust the 802.1p precedence of the received packets.
