a path between source A and Destination B goes through a sequence of physical networks $($pl$,$ p$2$p$3.$ p$4.$ p$5).$ Each of the physical networks PI$..$ P$5$ has a different MTU $(100,120,200,250,60)$Assign an MTU to cach of the physical networks so that only two routers perform fragmentationNET P$1$ P$2$ P$3$ P$3$ P$5$MTU
