ACI and L2TP?

[tlequertier]

Hello,

i have a Strange request and i would like to get an advice about it.

I have implemented a Dual Site ACI Fabric : DCI is a back to back (vpc) via DWDM. 

The question from my Customer is :  is it possible to establish a L2TP tunnel between a VRF define in the left side ACI Fabric and another VRF defined in the right side ACI Fabric ? 

We tried to bypass an issu we have with PVLAN that can't be extended between teh two ACI Fabrics :  the flows from an Isolated VM (PVLAN x)  in left ACI Fabric side can't reach a VM (standard VM (not PVLAN isolated) in the other (right ) Datacenter. because retrurning flows are dropped...on DCI 

Thanks a lot for your help

Hi

Have you looked into the "Common Pervasive Gateway" Feature in ACI?

Hello,

yes Pervasive GW is working fine. It is not my question.

My question is : is L2TP feature configurable into an ACI  (between 2 VRF located in two Dual Site ACI Fabrics) ?

Thanks a lot for your help.
