multipod mtu 9126 vs 9150

Hello everyone, we're looking into deploying a multipod ACI at multiple datacenters but the carrier will only support max MTU 9126...is this going to cause trouble, or will the deployment work as well as be supported?

 

Thanks

I believe this will not work, if you look at all the White Papers it says 9150. Not sure why it wouldn't work via 9216, but you have to remember that there are also stringent bandwidth and latency requirements "the maximum latency supported between Pods is 10 msec RTT, which roughly translates to a geographical distance of up to 500 miles."

Please see the following document.

Would need someone from Cisco to speak up here.
