Hello, I was wondering if anyone has any experience or knowledge regarding the performance impact of enabling ECMP for BGP on the VM-300 series appliance in Azure. Documentation stated that there is an impact to performance as the overhead associated is processed via software vs hardware, but no metrics were provided with that statement. Some info to help - we are only looking to use two paths, and there is probably around 20 prefixes advertised/received prior to enabling ECMP. Each BGP peer will also run over an IPSEC tunnel. I am trying to determine any potential performance impact as we are in the planning phase and have not provisioned a second circuit to which we would want to leverage ECMP to have a load balanced active/active path between our on premises and Azure. Any input is greatly appreciated.
