IP routing

Routing protocols

Dynamic routes are routes learned via routing protocols. Routing protocols are configured on routers with the purpose of exchanging routing information. There are many benefits of using routing protocols in your network, such as:unlike static routing, you don’t need to manually configure every route on each router in the network. You just need to configure the networks to be advertised on a router directly connected to them.if a link fails and the network topology changes, routers can advertise Read more […]

Administrative distance & metric

Administrative distanceA network can use more than one routing protocol, and routers on the network can learn about a route from multiple sources. Routers need to find a way to select a better path when there are multiple paths available. Administrative distance number is used by routers to find out which route is better (lower number is better). For example, if the same route is learned from RIP and EIGRP, a Cisco router will choose the EIGRP route and stores it in the routing table. This is because Read more […]

Connected, static & dynamic routes

Let’s explain the types of routes that can be found in a router’s routing table.Connected routesSubnets directly connected to a router’s interface are added to the router’s routing table. Interface has to have an IP address configured and both interface status codes must be in the up and up┬ástate. A router will be able to route all packets destined for all hosts in subnets directly connected to its active interfaces.Consider the following example. The router has two active Read more […]

What is IP routing?

IP routing is the process of sending packets from a host on one network to another host on a different remote network. This process is usually done by routers. Routers examine the destination IP address of a packet , determine the next-hop address, and forward the packet. Routers use routing tables to determine the next hop address to which the packet should be forwarded.Consider the following example of IP routing:Host A wants to communicate with host B, but host B is on another network. Host A Read more […]
