Electronic Devices Raza Zaman , Johri Abdullah, Farhan Nisar, Samad Baseer 5 2 2016 Random nodes movement in GNS3 shows degradation in the network performance due to communication between IPV4 to IPV6. The communication process from one node to another node consumes time that related to control packets. In static networks, the chances of failure networks are due to bad configuration. However, in GNS3, the main reason for the topology change is caused by the nodes movement with different kinds of protocols and shares their information respectively.
