Question 3: In general, routing protocols perform two tasks: (a) collect/ disseminate network state information and (b) compute paths using this information and fill the routing table at each node. Recall that we have two different yet complementary routing protocols in the Internet, namely intra-domain routing protocol OSPF and inter-domain routing protocol BGP a. Giving an example, explain how OSPF works (i.e., performs the above tasks). b. Giving an example, explain how BGP works (i.e., performs the above tasks). c. Briefly explain why we need two different routing protocols in the internet
