Network Scenario: Above mentioned diagram depicts the network scenario of a National pharmaceutical company having different types of dynamic Routing protocols (RIP, OSPF & BGP) running on its Head office, Sub-Division, Branch Offices and ISPs Routers. TASKS: As per theoretical concepts, first of all decide & discuss which routing protocol is best suited in this hybrid scenario and why (Reason)? Further after deciding the right protocol placements, explain how could above mentioned Routing protocols talk to each other as different routing protocols cant directly communicate each other. Perform that appropriate router configuration through which HO, SD, BO & ISPs routers having different routing protocols could communicate each other in the above hybrid scenario.
