Which routing protocol depends on the DUAL algorithm to calculate the shortest path to a destination
Which algorithm is run by link-state routing protocols to calculate the shortest path to destination networks?
Dijkstra
What does the Cisco IOS use to calculate the OSPF cost to a destination network?
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
What is an IP routing algorithm?
An IP routing algorithm is routing used for IP networks to forward datagrams over a network. You can learn more about IP routing algorithms at the Wikipedia.
Can a routing table in a datagram network have two entries with the same destination address?
In a datagram network, the destination addresses are unique. They cannot be duplicated in the routing table.
Where is the routing?
It is the process of forwarding packets in a network so that it reaches its intended destinations. To perform routing there are numbers of routing algorithm .

What is sink tree in routing?
Sink Tree is a description in a routing table of all the paths in a network to a destination.
What two metrics are used by EIGRPs routing algorithm to calculate route metrics?
Delay and bandwidth
What is dynamic routing?
Routing refers to the process of moving packets of information across a network. Static and dynamic routing are the two types of routing algorithms used for this transfer of information.The term routing encapsulates two tasks. These tasks are deciding the paths for data transferred and sending the packets on these paths. The routing is a process that is a function carried out at layer 3 of the OSI reference model. The routing algorithm decides the output line to transfer the incoming packets. The routing algorithms are based on the routing protocol that uses metrics to assess whether a particular path is the optimal path available for transfer of the data packets. The metrics used for evaluating the paths are bandwidth, delay and reliability. The routing algorithms use these protocols to determine an optimal path from the source to the destination. The routing tables maintain all the information related to routing. There are various routing algorithms and depending on these routing algorithms, the information stored in the routing table varies. Every router has its own routing table and it fills this table with the required information to calculate the optimal path between the source router and the destination router. To understand the basic points of static vs dynamic routing, let us get to know what are routing tables.Routing tableA routing table is a document stored in the router or a network computer. The routing table is stored in the form of a database or is simply a file stored in the router. The data entered in the routing table is referred to when the best possible path to transfer information across two computers in a network is to be determined. The two classifications, viz., static and dynamic routing, are based on the way in which the routing tables are updated every time they are used. The routers in which the data is stored and updated manually are called static routers. On the other hand, the routers in which the information is changed dynamically, by the router itself, are referred to as dynamic routers. Let us compare the two types of routing algorithms based on the static and dynamic routing algorithm used, in the static vs. dynamic routing section given below.Static Vs. Dynamic RoutingStatic routing manually sets up the optimal paths between the source and the destination computers. On the other hand, the dynamic routing uses dynamic protocols to update the routing table and to find the optimal path between the source and the destination computers.The routers that use the static routing algorithm do not have any controlling mechanism if any faults in the routing paths. These routers do not sense the faulty computers encountered while finding the path between two computers or routers in a network. The dynamic routing algorithms are used in the dynamic routers and these routers can sense a faulty router in the network. Also, the dynamic router eliminates the faulty router and finds out another possible optimal path from the source to the destination. If any router is down or faulty due to certain reasons, this fault is circulated in the entire network. Due to this quality of the dynamic routers, they are also called adaptive routers.The static routing is suitable for very small networks and they cannot be used in large networks. As against this, dynamic routing is used for larger networks. The manual routing has no specific routing algorithm. The dynamic routers are based on various routing algorithms like OSPF (Open Shortest Path First), IGRP (Interior Gateway Routing Protocol) and RIP (Routing Information Protocol).The static routing is the simplest way of routing the data packets from a source to a destination in a network. The dynamic routing uses complex algorithms for routing the data packets.The static routing has the advantage that it requires minimal memory. Dynamic router, however, have quite a few memory overheads, depending on the routing algorithms used.The network administrator finds out the optimal path and makes the changes in the routing table in the case of static routing. In the dynamic routing algorithm, the algorithm and the protocol is responsible for routing the packets and making the changes accordingly in the routing table.Nowadays, the static routing is seldom used. With the technological advancements, the dynamic routing is used to route the packets in the network, efficiently. Thus, the above algorithm explains routing, routing tables and static vs dynamic routing.
When multiple routing protocols have a route to the same destination network what determines which routers installed in the routing table?
the distance vector metric
How do you calculate metrics?
Hop count & administrative distance. This is a measure used by the routing protocol to calculate the best path to a given destination, if it learns multiple paths to the same destination. Each routing protocol uses a different metric.
