    Hi, great byte size video. I did not understand why you had to create the subnet: 0.0.0.0/0 inside the aci? Shouldn’t that be learned over ospf from the router?

      Great question Sandev, the subnet defined within the External EPG is to define the destination IP addresses required for the contract (ACL) between your external and internal EPGs. You can define multiple External EPGs to an L3out each with different defined subsets, allowing for granularity of control to different external networks.
