B. Host information collection
C. Local proxy ARP
D. ARP broadcast suppression

Answer: B,C,D

Explanation:
VXLAN networkssuffer from ARP floodingbecause ARP requests arebroadcasted across all VTEPsin a Layer
2 domain. Toreduce ARP flooding, the following mechanisms can be enabled:
#A. Local Proxy ARP
Allows the local VTEP to respond to ARP requests without forwarding them across the VXLAN network.
The VTEPcaches MAC-IP mappingsand replies directly to ARP requests, reducing unnecessary flooding.
#B. ARP Broadcast Suppression
Converts ARP broadcast packets into unicast or multicast packetsto minimize network-wide flooding.
#C. Host Information Collection
Collects and stores MAC-IP bindings of endpoints, which can be used by proxy ARP to reduce flooding.
#D. Port Isolation
Port isolation prevents communication between devices within the same VLANbut doesnot help reduce ARP floodingbetween VTEPs.
