Text from Source: In this scenario, the Layer 3 (L3) gateway is configured on the same vPC pair and acts as the DCI. In order to isolate the HSRP, you must configure a Port Access Control List (PACL) on the DCI port-channel and disable HSRP Gratuitous Address Resolution Protocols (ARPs) (GARPs) on the Switched Virtual Interfaces (SVIs) for the VLANs that move across the DCI
