Statement introduced in Junos OS Release 19.1R1 for MX Series Routers.


Configure the maximum receive unit (MRU) of the interface in bytes. The maximum receive unit of an interface indicates the largest size of a packet that the interface can accept. You can configure the parameters so that the value of MRU equals the value of MTU. You can also configure different values for MRU and MTU. When a device receives packets whose size is greater than the interface MRU, those packets are dropped by the device’s forwarding plane.
