Configuring Protocol Independent Multicast (PIM) anycast RP allows for efficient multicast traffic routing between pods by having multiple Rendezvous Points (RPs) share the same IP address. A maximum multicast range of /15 provides sufficient address space to support the scale of multicast traffic typically required in such deployments. References := (Implementing Cisco Application Centric Infrastructure Official Cert Guide)

 Enabling endpoint loop protection is the action that prevents frequent MAC and IP address moves between different leaf switch ports. This feature helps to identify and mitigate loops within the network, which can cause these frequent address moves. By detecting and blocking the looped interfaces, it stabilizes the network and stops the address flapping.

To limit IP address learning in BD1 when VM1 is incorrectly attached to a PortGroup, enabling the Enforce Subnet Check is the correct action. This feature ensures that only IP addresses belonging to the defined subnets under the bridge domain are learned, preventing incorrect IP data from being disseminated across the network. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

Within Cisco ACI, when a Topology Change Notification (TCN) BPDU is received in a VLAN, the system flushes the endpoints for the associated encapsulation to ensure network stability. Additionally, BPDU filter and BPDU guard can be configured on Cisco ACI leaf edge ports to protect against potential STP issues2.
