Создание TenantYou can ”partition” your ACI Fabric & have up to 3000 Tenants even
using the same IP subnets with no conflict

different IP subnets to each (Prod, Test, etc)

Create Application ProfilesAn Application Profile is a graphical representation of our network configuration. Think of it as a “folder of VLANs” at the Fabric level.
A Tenant may have multiple Application Profiles
Unclear network connectityShow VLAN would show all and every VLAN per-Switch
without understanding how they connect between each other

Группа: Набор VM или физических серверов с одинаковой политикой1.
Контракт: Набор правил (ACL) взаимодействия между группами2.

Создаем End Point Groups (EPGs)We will create an EPG and name it just as we would with a VLAN. You may also add one Bridge Domain per EPG with an IP address (just like
an SVI) in case you want ACI Anycast Gateway functionality
Создаем VLANAdd VLANs per Switch, name each of them and then
configure trunks to extend connectivity. Additionally configure HSRP/VRRP for Gateways at the distribution/core layer

Create L3 OutSpecify on which leaf and port of the fabric you want to enable external
routing. Those routes will be imported inside the ACI Fabric with BGP (auto-configured) and Spines will serve as Route Reflectors. L3 Outs need a
contract to communicate to EPGs and BDs need to be associated to L3 Outs
