the ESXi hosts are on the 172.16.101.x

the vmkkenal vmk ports are on 172.16.10.x and  the gateway for the VMKernal vmotion is 172.16.101.1

Can the IP Addresses of your vMotion VMKernel Portgroups communicate with each Host across the network?

e.g. can you ping 172.16.10.x from each Host?

are they reachable?

it also depends on which vSwitch and networking you have, e.g. VLANs dedicated vMotion network.

Are Host and vMotion on the same LAN?

well they are technically on the same network segment  , so the gateway does not matter?

but just the same i see the other esxi servers here are set to the same network segemtn for the gateway and ip


like vMK kernal 172.16.101.18 and the gateway would be 172.16.101.1

Also, just as a best practice for security reasons, the VMotion network should be a non-routable network since this data is not being encrypted.
