Cisco ACI L3OUT

[conf-t]

Hi,

Please, what is the difference between :

• Add new logical interfaces to an existing l3out to an external router
• Create new l3out to the same external router..

FYI: will be a new VRF on the external router side.. 

Thanks,

Hi @conf-t ,

Your comment that it will be a new VRF on the external router side begs the question
Will there be a different VRF in ACI?

If you have a different VRF in ACI (I'm struggling to think of how this would look if you didn't) then the answer is easy - you'll need two L3Outs in ACI because a L3Out can only be linked with a single VRF.

In fact, I think all-round that this is probably the better approach, but I'm happy to be corrected.
