The correct answer is A. Configure the links between the access switches and the distribution switch as a trunk port. Access interfaces in an L2PT-enabled VLAN should not receive L2PT-tunneled PDUs. If an access interface does receive L2PT-tunneled PDUs, there might be a loop in the network, and the device will shut down the interface. protocol-tunneling.html
Question
Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down. Which action would solve this problem?
Exhibit
Options
- AConfigure the links between the access switches and the distribution switch as a trunk port.
- BDisable the BPDU block function on the access switches.
- CDisable the BPDU block function on the distribution switch.
- DConfigure a GRE tunnel to encapsulate the L2PT traffic across the WAN.

Explanation
Access interfaces in an L2PT-enabled VLAN should not receive L2PT-tunneled PDUs. If an access interface does receive L2PT-tunneled PDUs, there might be a loop in the network, and the device will shut down the interface. protocol-tunneling.html
