Best Path
The route the driver took was more efficient, than the other driver. In the sentence, route refers the path the driver drove on.
In this case, 'network' refers to a specific network prefix, such as 192.168.0.0/24 or 10.0.0.0/8. 'Advertising a network' typically refers to announcing a route for that network prefix into a routing protocol, most commonly BGP (but this term is sometimes also used when working with IGPs such as OSPF and IS-IS). In other words, if your network prefix is 172.16.0.0/24 and you want other networks to be able to reach your network, you advertise a route for 172.16.0.0/24 into the appropriate routing protocol, which allows the other networks to know how to find you. It's kind of like giving all your friends your home address, all at once.
Because dynamic routing automatically selects the most efficient route between nodes, reducing the possibility for human error
The route via Path B is installed because the EIGRP route has the best metric to network 10.2.0.0/16. The route via Path A is installed because the static route has the best metric to network 10.2.0.0/16. The route via Path B is installed because the EIGRP route has the lowest administrative distance to network 10.2.0.0/16. The route via Path A is installed because the static route has the lowest administrative distance to network 10.2.0.0/16.
INHALATION
Router2 is missing a route to the 172.16.0.0 networkRouter3 is missing a route to the 10.0.0.0 network
Layer 3 addressing is hierarchical because it allows the division of networks into subnets. For example, one route entry can refer to a large general network and another can refer to a subnet of that same network. When forwarding a packet, the router will select the most specific route that it knows. However, if a specific subnet is not in the routing table but the larger network that holds the subnet is known, then the router will send it to the larger network, trusting that another router will find the subnet.
The network layer uses IP addresses to determine whether or not to route a packet from one network to another. Since an IP address has two parts, the network id and the host/client id, this makes it a natural fit (IP addressing) for the network layer.
VLSM (Variable Length Subnet Mask) Allows more than one subnet mask to exist within a network allows subnetting of an already subnetted network address. More Efficient use of IP addresses- Without the use of VLSM, companies must implement a single subnet mast within an entire Class A, B, or C network number. Greater capability to use route summarization - VLSM allows more hierarchical levels within an addressing plan and thus allows better route summarization within routing tables. Isolation of topology changes from other routers- Another advantage to using VLSM enabled route summarization in a large, complex network is that it can isolate topology changes from other routers.
The routing process is the process by which network traffic is sent across a network by the most efficient route. Routing involves selecting the path that each individual data stream will take and then ensuring that it follows that path. The process is automated and run entirely by software in the modern day.
Route planning software is used to find the best route to a specific location. It can be used by businesses such as delivery companies to find the most efficient route.
