Consider the following statements about the functionality of an IP based router.
I. A router does not modify the IP packets during forwarding.
II. It is not necessary for a router to implement any routing protocol.
III. A router should reassemble IP fragments if the MTU of the outgoing link is larger than the size of the incoming IP packet.
Which of the above statements is/are TRUE?
I and II only
I only
II and III only
II only
Statement I: False, The router does modify the IP packets, the TTL is decreased at routers while transmitting.
Statement II: True, The routers can transmit data in all direction without implementing any routing protocol.
Statement III: False, The router is not responsible for reassembling. This process is done at the destination.
On the other hand router performs fragmentation when the incoming package size is greater than the Maximum Transmission Unit (MTU) of the transmission link.
