Cisco Exam 300-615 Topic 2 Question 87 Discussion

"A network engineer troubleshoots an issue at a Cisco data center environment with these conditions:

* The data center has Cisco Nexus 9000 Series Switches running the vPC setup.

* The gateway of the servers is an HSRP IP address between the VLAN interfaces configured on both Cisco Nexus switches.

* Some of the client application servers are implementing fast-path forwarding for the return traffic.

* Those servers are sending the return traffic to the VLAN interface MAC address instead of the HSRP MAC address.

The network engineer discovers that some traffic is dropped because it passes the vPC peer link to be forwarded out the vPC interface. What must be configured on the vPC switches to resolve the issue?
