8. Consider the IPV4 header with default 32 bits words, TOS as 0, datagram length as 98 bytes, 35840 as identification, no need of any fragmentation consideration, upper limit of routers are 64 and send this datagram using TCP/IP. The source IP address is 196.159.196.20 and destination address is 179.134.21.169. Compute an IP header checksum and also verify at the destination. 7. Describe the Link State Routing Algorithm and briefly describe how the routing table updates by using LSR algorithm for the network shown in the figure below and indicate all the steps taken by node D as a source until it establishes the shortest path route to every other node in the network. Each column should be used to describe one iteration of the protocol. 5 3 B 5 A 2 1 EF3 3 1 2 EE 1
