ACI - Benefits of Gateway on BD and Gateway on External Device

[ADC Lane]

Hi team,

In my understand, if using BD as Gateway in ACI,  this is common way to deploy, And using for migration from tradition network to ACI. 

And I can use Gateway in external devices (ACI is just L2 switches) 

(Maybe my knowlegdes is wrong   ! )

I am still so confuse about 2 options when use them in real practice.

Could you help explain more detail about benefits of Gateway in BD than Gateway in External devices ? (pros and cons of each others) 

Thank you in advance !

Hi @ADC Lane ,

I saw your post while I was on leave - and hoped someone would answer it before now.

If you are using ACI as L2 only, best practice is to NOT configure any L3 addresses on ACI.

If you want to take advantage of the advanced features of ACI, (contracts, Policy Based Redirection, integrated Virtual Machine Management, painless IPv4>IPv6 migration etc) you'll need to migrate your default gateways to ACI.

Yes - that is possible and a common solution.  You just need to map the existing VLANs as used in VMware to EPGs in ACI - just like you would if they were physical servers attached to physical switches.
