L3 Subinterfaces on Dell Z9100

Hi Team,

While configuring the Dell Switches (Z9100, acting as a Spine switch) we need to configure the uplink ports.

We are having around 6 VRFs.

The site router (to which uplinks will connect) do not want to configure the VLANs and want to configure L3 Subinterfaces for each VRF.

We have a port channel from Dell to Site Routers on which traffic for all 6 VRFs will be required to be configured.

Do someone have configuration to create L3 subinterfaces, where each subinterface will be part of one VRF,  for the port channel.

Thanks !!
