We have VNF application on NSX platform. It has multiple VMs work as line cards. The network planes that each VM connect to are same.
The same plane on different VM can not set the same subnet IP address, for the VNF application is based on router architecture.
But the LIF of DLR can only set one IP address, so it can not connect to all the line cards VM of application.
Of cause, ESG can support this, but if we use ESG, then the east-west traffic will have to be sent to ESG, it will consume the north-south bandwidth. We don't want this happen.
So if DLR's LIF can support multiple IP addresses and ECMP, we'll be very happy. ^_^
