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.
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.
A router learns two paths with equal metrics to a destination network via the RIP routing protocol How will the router handle packets to the destination network?
The router will install both routes in the routing table and load balance between the two.
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
A router that uses the RIP routing protocol has an entry for a network in the routing table It then receives an update with another entry for the same destination network but with a lower hop count?
it will append the update information to the routing table

Which routing algorithm does EIGRP use to calculate the best path to a destination within a network?
DUAL
When forwarding a route which route will router select?
First, routing is the process a router performs when making forwarding decisions for each packet arriving at the gateway interface. To forward a packet to a destination network, the router requires a route to that network. If a route to a destination network does not exist on the router, the packet will be forwarded to the default gateway. Now, the destination network can be a number of routers or hops away from the default gateway. If the router has an entry for the network in its routing table, it would only indicate the next-hop router to which the packet is to be forwarded to and not the exact route to the final router. To sum it up, the routing process uses a routing table to map the destination address to the next hop and then forwards the packet to the next-hop address.

What is the final step in the link state routing process?
SPF computes best path to each destination network
Which information must a router have in order to perform proper and efficient routing?
Destination network address of an incoming packet
What is work to router?
Electronic messages sent between computer networks are stored in the router, while it determines all of the possible paths to the destination address. The router then chooses the most expedient route, based on its investigations into the traffic load, distance, number of network points that the packet has to pass through, and cost algorythms between computer networks, before forwarding the packet to the final destination. Router hardware is a physical device which connects the local area network to the wide area network, it is responsible for routing network traffic from source to destination. These routers run on layer routing protocols and operate on network layer information.
