Consider a network of 8 routers connected together to provide more than one path

Question

Consider a network of 8 routers connected together to provide more than one path of connectivity between host A and host B at two different locations. In order for these routers to understand the various available paths in the network, they are all running a link state routing protocol. What statement is true about this configuration:

A.The routers will only transmit packets generated by the link-state protocol.

B.The routers will transmit the headers of packets only.

C.The routers will transmit packets with client’s data and packets generated by the link-state protocol.

D.The routers will transmit the payload and checksum fields of packets only.

Explanation / Answer

-> Link state routing protocol :

         In this routing , only connectivity related information transmitted between hosts in the network. Every time verifies neighbour nodes correctly routed or not by flooding messages related to connectivity.

So , option

A.The routers will transmit packets only generated by link state protocol. is correct answer.

Option B. is not correct because link protocol sends Hello message to all nodes to verify connectivity,it shows only header data is not transmitted.

Option C. is not correct answer because link state routing transmits only connectivity information ,not transmits client data.

Option D. is not correct answer because payload and checksum are extra information for node integrity and data authenticity of data node. But link protocol transfers connectivity related information between nodes.

So only option A. Packets generated by protocol are only transmitted between nodes. is the correct answer.
