@mutahhardar795 -- @30:56 -- Second fragment typically will not have L4 header ?- In IP fragmentation, the Layer 4 (Transport Layer) information is typically found in the header of the first fragment. The subsequent fragments usually contain only a portion of the original Layer 4 payload and lack the complete Transport Layer header.

For complete explanation, which of your course i need to purchase

Sir i have a huge doubt 😢please clear me Consider two routers ! One packet needs to gone out from one interface[egress interface] of R1 Router and same packet needs to be get into R2 [ ingress interface ] These two interfaces are in facing one to one with each different router.one ethernet cable is connecting those two interface If the the two interfaces MTU values are miss matched or missconfigured different values then what would be happen ? What will be the scenerio ? You are explaining about egress interface MTU only but here you did not tell about the ingress interface MTU of the router !!!

Sir i have another doubt ! When we we are going to buy a router they will say this router interfaces will support 10 mb/s , 100mb/s , 1Gb/s Please let you know clearly in one video !!! Please we need a video for interface speed !!! Is there any relationship between packet MTU size and speed of that router ?????? We need video sir Speed of the interface means what they mentioned ? When we connect two routers interface how they negotiate speed ? Relationship between interface speed & ISP bandwidth speed and MTU size ?

9:44- it should be L4 instead of L2
