Yes, you can configure different MTU on different subinterfaces. Router checks the MTU from the main interface.

Yes, you can configure different MTU on different subinterfaces. Router checks the MTU from the main interface. If the main interface MTU is lower value than the MTU on the subinterface, the router changes the MTU on the main interface to match with the subinterface.
