A leaf is programmed with the correct VLANs and interfaces, but the servers in web EPG are unreachable from the outside Layer 2 network. You use a unique external L2out EPG as a Layer 2 extension inside the Cisco ACI fabric.
Which action do you take to resolve the communication issue?
A. Bind the web EPG to a port/leaf.
B. Configure contracts between the web EPG and the L2out EPG.
C. Configure an MTU of 9000 bytes on the devices in the L2out EPG.
D. Enable a spanning tree on the VLANs on the leaf.
