hello, we are planning to migrate an existing datacenter L3 environment into ACI. The environment consists of approx 250 VRFs (with each 10-20 vlans) in the old world and due to the size of the environment Firewalls that act as North/South and East/West.
the main point i am wondering is how we could setup the VRFs in the best way in ACI. i don´t mind if we use VRFs, tenants or ESG´s...but from technical perspective i am wondering what could be the best way to setup the corrct communicaiton path. today we use default routes to get connectivity out of the VRF to the bug world. but in ACI we do nnot have default routes in a native way.
mabye somebody has some experience here.
