MTU Size for HCX between 2x VMC on AWS SDDC's

[virtualizingtheworld]

Hi,

What MTU size is recommended on directConnect interface for HCX traffic flowing between SDDC's via VTGW?

Thanks

Not sure where my reply went. 

You can run 8500: https://www.vmware.com/docs/an-introduction-to-vmware-transit-gateway-for-vmware-cloud-on-aws

Whether or not you'll see an improvement running beyond 1650 depends on many factors there are HCX overheads to account for.

Thanks, and no other change is needed within NSX-T or vCenter within VMC on AWS to support an MTU of 1650 end to end right?

Want to optimize migration time as some VMs will be 10TB or more.

Thanks
