Unformatted text preview: paths to different gateway routers. RIP Routing Information Protocol Uses hop count as the counting metric. Shortest path consists of least number of hops from a router to a destination subnet. Each link has a value of one. Distance Vector type algorithm Usually used in lower tier ISPs. OSPF Open Shortest Path First Dijkstras shortest path algorithm. Broadcasts link state to all routers within an AS. Multiple shortest paths can be used to send a load of data if they are equal in value. Hierarchal Routing is possible using areas which contain their own OSPF routing algorithm. Area border routers are responsible for forwarding data outside of own area. Backbone area runs an inter-OSPF protocol to move data between OSPF areas. Boundary Router performs BGP to communicated with outside AS routers....
