The best route is the longest match route to the destination IP address. The route lookup process matches the destination IP address with the route available in the routing table and chooses the longest match route as forwarding route. To match the destination IPv4 address of a packet with the routes in the routing table; […]
The routers are typically responsible for directing traffic across multiple networks. Each router maintains a list of known network and directions calling routing table. The router performs a routing table entries lookup to find the proper interface that leads to the destination address. Each entry in a routing table called a “route entry: or “route”. […]
There are only two routing protocols use link-state, Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) share many similarities and also have many differences. Both routing protocols provide the necessary routing functionality. Open Shortest Path First (OSPF) The Open […]
There are several advantages and disadvantages of link-state routing protocols compared to distance vector routing protocols. In this article, we are going to discuss the advantages and disadvantages of a link-state routing protocol. Advantages of link-state Fast Network Convergence– Fast network convergence is the main advantage of the link-state routing protocol. Because on receiving an […]
Link-state routing protocols are also known as shortest path first protocol. It maintains a complete picture of all the router running a link-state routing protocol in the complete network. All routers running a link-state routing protocol originates information of itself and its directly connected routers, links, and the state of those links as multicast messages. […]
