In ACI, the logic to define a virtual Port-Channel is as follows:

• The infrastructure administrator creates the VPC domain from the "Access Policies” as "protection" policy (i.e. which "nodes" are part of a vPC domain)
• The infrastructure administrator defines the "Access Policy Group" "Bundle Interfaces" where one creates the specific vPC channel-group configuration
• The interface policy defines a list of interfaces that are associated with the vPC channel-group but it doesn’t specify which leafs this is associated with
• The switch policy defines a list of "nodes" nodes whose interfaces selected by the interface policy are defined as part of the vPC

When the ingress leaf switch receives the frame, it learns the source MAC and source IP and programs them into the local station table. The leaf switch derives the source EPG based on the VLAN ID or VXLAN VNID. The MAC and IP addresses in the local station table also contain the EPG information and they can be used to derive EPG information for the subsequent packets.

When a leaf switch receives a frame from the host it needs to determine whether the destination IP is inside the fabric or outside the fabric. If the destination IP matches with any /32 host route entry in the global station table, it means the destination is an endpoint inside the fabric and the leave switch already learned the endpoint.

Private-L3 - Equivalent to a VRF, separates routing instances, can be used as an admin separation
