The first Catalyst switch should be configured with a hostname of SW1, and the second Catalyst switch should have a hostname of SW2.
Configure all the ports, except F0/19 and F0/20, in shutdown mode:
Ports F0/19–20 on both switches should be in trunking mode. These ports should use an industry-standard protocol to establish the trunk.
Create VLANs 12, 34, 56, and 90 on SW1 and ensure these VLANs are propagated to SW2 via VTP messages. Use any name to accomplish this task.
Configure Multiple-Instance Spanning Tree on these two switches using the following policies:
There should be two instances of STP:
instance 1 and 2.
The revision number should be 1.
The MST region name should be CCIE.
Instance 1 should handle VLANs 12 and 34.
Instance 2 should handle VLANs 56 and 90.
All future VLANs should use instance 0.
Instance 1 should use F0/19.
Instance 2 should use F0/20.
SW1 should be the root bridge for the first instance.
SW2 should be the root bridge for the second instance.
