The feature allows middle routers to intercept and alter this value if configured to do so as a technique to avoid MTU problems mentioned above. Lastly, MRU? On the other hand maximum receive unit (MRU) is the largest packet size that an interface can receive , so it’s an ingress interface parameter.

A larger MTU (Maximum Transmission Unit) brings greater efficiency in transmitting because each packet carries more data; however, a packet too large may be fragmented and results in lower transmitting speed instead.
