Hello guys

Pls the Below inquiries 

In the BD Settings

L2 Unknown unicast = Flood     ===?What This For

ARP Flooding = True ==it means we flood inside the BD for a Particular MAC Address Instead of Spine Proxy

 

where do we need this 8021P? which devices need to be native Native ?

Hi Ibrahim,

L2 Unknown Unicast : "Flood", enabling flooding mode: if the destination MAC address is not known, flood in the bridge domain. By default, ARP traffic is not flooded but sent to the destination endpoint. For L2 Unknown Unicast is "Flood", ARP Flooding has to be set to true. By enabling ARP flooding, ARP traffic is also flooded.

Regarding 8021P: Kindly refer Section "Native 802.1p and Tagged EPGs on Interfaces"
