We are in the process of building a new large VCF deployment for a client.
Their network team have asked us to use the load-balance algorithm ‘Route-based-on-IP-hash’ on the DVS.
I know the differences based on the vSphere documentation but i’m lacking the experience of a real world deployment using that algorithm.
My particular area’s of interest are how do you cope with situations *before* you can math the algorithm on both the dvs and the physical switch.
For example during a VCF deployment the initial ESXes are deployed through VIA with a standard vswitch and ‘Route Based on Originating Virtual Port’
After that the CloudBuilder deploys a vcenter/dvs with teaming setting to ‘Route Based on Physical NIC Load’
I’ve seem from testing in my lab that this can cause serious issues, described in the fifth paragraph here:[https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-523FDFBD-EAEC-44A5-9451-F63EB792F156.html](https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-523FDFBD-EAEC-44A5-9451-F63EB792F156.html)
Is ‘Route based on IP-hash’ even officially supported with VCF?
Does anyone have experience with this algorithm they like to share?
