Configuring static routes

Configuring static routes 
6.1.3
This page lists the steps used to configure static routes and gives an example of a simple network for which static routes might be configured.
Use the following steps to configure static routes:
Step 1 Determine all desired prefixes, masks, and addresses. The address can be either a local interface or a next hop address that leads to the desired destination.
Step 2 Enter global configuration mode.
Step 3 Type the ip route command with a prefix and mask followed by the corresponding address from Step 1. The administrative distance is optional.
Step 4 Repeat Step 3 for all the destination networks that were defined in Step 1.
Step 5 Exit global configuration mode.
Step 6 Use the copy running-config startup-config command to save the active configuration to NVRAM.
The example network is a simple three-router configuration. Hoboken must be configured so that it can reach the 172.16.1.0 network and the 172.16.5.0 network. Both of these networks have a subnet mask of 255.255.255.0.
Packets that have a destination network of 172.16.1.0 need to be routed to Sterling and packets that have a destination address of 172.16.5.0 need to be routed to Waycross. Static routes can be configured to accomplish this task.
Both static routes will first be configured to use a local interface as the gateway to the destination networks. Since the administrative distance was not specified, it will default to 1 when the route is installed in the routing table.
The same two static routes can also be configured with a next-hop address as their gateway. The first route to the 172.16.1.0 network has a gateway of 172.16.2.1. The second route to the 172.16.5.0 network has a gateway of 172.16.4.2. Since the administrative distance was not specified, it defaults to 1.
The Lab Activity will help students learn how to configure static routes.
The next page will explain how default routes are configured.

OSI layers / Peer-to-peer communications / TCP/IP model

OSI layers 2.3.4 This page discusses the seven layers of the OSI model. The OSI reference model is a framework that is used to understand how information travels throughout a network. The OSI reference model explains how packets travel through the various layers to another device on a network, even if the sender and destination have different types of network media. In the OSI reference model, there are seven numbered layers, each of which illustrates a particular network function. - Dividing the network into seven layers provides the following advantages: • It breaks network communication into smaller, more manageable parts. • It standardizes network components to allow multiple vendor development and support. • It allows different types of network hardware and software to communicate with each other. • It prevents changes in one layer from affecting other layers. • It divides network communication into smaller parts to make learning it easier to understand. In the foll...

Advantages and disadvantages of link-state routing

Advantages and disadvantages of link-state routing 2.1.5  This page lists the advantages and disadvantages of link-state routing protocols. The following are advantages of link-state routing protocols:  Link-state protocols use cost metrics to choose paths through the network. The cost metric reflects the capacity of the links on those paths. Link-state protocols use triggered updates and LSA floods to immediately report changes in the network topology to all routers in the network. This leads to fast convergence times. Each router has a complete and synchronized picture of the network. Therefore, it is very difficult for routing loops to occur. Routers use the latest information to make the best routing decisions. The link-state database sizes can be minimized with careful network design. This leads to smaller Dijkstra calculations and faster convergence. Every router, at the very least, maps the topology of it...
