You have created redundant paths between four switches in the Executive Office building, and you'd like to manually determine which switch will serve as the root bridge.

Each switch has the default spanning tree bridge priority of 32768. The root bridge is determined by the switch with the lowest bridge ID. The bridge ID is the priority number and MAC address assigned to the switch. To configure SwitchA as the root bridge, you could use a priority value of 4096 through 28672.

The switches have the following MAC addresses:
N/A

In this lab, your task is to complete the following:
Configure SwitchA to be the root bridge for VLAN 1.
Save your changes to the startup-config file on each switch that has configuration changes.
Each switch has the default spanning tree configuration. After the correct configuration is applied, SwitchA's Fa 0/1-3 interfaces will be in the designated state. Use the show spanning-tree vlan 1 command to verify the configuration.

Complete this lab as follows:
1. Press Enter.
2. At the prompt, enter:
SwitchA>ena
SwitchA#conf t
SwitchA(config)#spanning-tree vlan 1 priority 4096
SwitchA(config)#exit
SwitchA#copy running-config startup-config
3. Press Enter.
