Windows 2008 routing and remote access lan routing

The biggest problem is that after those computers go out of your safe environment, they are brought back into work the next day and are plugged into your organizational network.

Sign in. Your cart. Before we start configuration, check ping from Windows 10 machine to Domain Controller. Ping Open Server Manager Console. Select Role-based or feature-based installation and click Next. Select a server from the server pool on which you want to install the Remote Access Service role, click Next. On select server roles page, select the Remote Access Service checkbox. Click Next. To keep track of the various routes in a network, routers create and maintain routing tables.

Routers communicate with one another to maintain their routing tables through a routing update message. The routing update message can consist of all or a portion of a routing table. By analyzing routing updates from all other routers, a router can build a detailed picture of network topology. Static routing algorithms are hardly algorithms at all, but are table mappings established by the network administrator prior to the beginning of routing.

These mappings do not change unless the network administrator alters them. Algorithms that use static routes are simple to design and work well in environments where network traffic is relatively predictable and where network design is relatively simple. Most of the dominant routing algorithms are dynamic routing algorithms , which adjust to changing network circumstances by analyzing incoming routing update messages.

If the message indicates that a network change has occurred, the routing software recalculates routes and sends out new routing update messages.

These messages flow through the network, stimulating routers to rerun their algorithms and change their routing tables accordingly. Routers use distance-vector—based routing protocols to periodically advertise or broadcast the routes in their routing tables, but they send it to only their neighboring routers. Routing information exchanged between typical distance-vector—based routers is unsynchronized and unacknowledged.

Distance-vector—based routing protocols are simple and easy to understand and easy to configure. The disadvantage is that multiple routes to a given network can reflect multiple entries in the routing table, which leads to a large routing table.

In addition, if you have a large routing table, network traffic increases as it periodically advertises the routing table to the other routers, even after the network has converged.

Last, distance-vector protocol convergence of large internetworks can take several minutes. Link-state algorithms are also known as shortest path first algorithms. Instead of using broadcast, link-state routers send updates directly or by using multicast traffic to all routers within the network. Each router, however, sends only the portion of the routing table that describes the state of its own links. In essence, link-state algorithms send small updates everywhere. Because they converge more quickly, link-state algorithms are somewhat less prone to routing loops than distance-vector algorithms.

In addition, link-state algorithms do not exchange any routing information when the internetwork has converged. They have small routing tables because they store a single optimal route for each network ID.

On the other hand, link-state algorithms require more CPU power and memory than distance-vector algorithms. Link-state algorithms, therefore, can be more expensive to implement and support and are considered harder to understand. A popular routing protocol is the Routing Information Protocol RIP , which is a distance-vector protocol designed for exchanging routing information within a small- to medium-size network.

The biggest advantage of RIP is that it is extremely simple to configure and deploy. RIP uses a single routing metric of hop counts number of routers to measure the distance between the source and a destination network. Each hop in a path from source to destination is assigned a hop-count value, which is typically 1.

When a router receives a routing update that contains a new or changed destination network entry, the router adds one to the metric value indicated in the update and enters the network in the routing table.

Because RIP uses only hop count to determine the best path to an internetwork. If RIP finds more than one link to the same remote network with the same hop count, it automatically performs a round-robin load balance. RIP can perform load balancing for up to six equal-cost links.

However, a problem with using hops as the only metric is when two links to a remote network have different bandwidths. For example, if you have one link that is a 56KB switched link and a T1 running at 1. This is known as pinhole congestion. To overcome pinhole congestion, you have to design a network with equal bandwidth links or use a routing protocol that takes bandwidth into account.

RIP prevents routing loops from continuing indefinitely by implementing a limit on the number of hops allowed in a path from the source to a destination. The maximum number of hops in a path is If a router receives a routing update that contains a new or changed entry, and if increasing the metric value by one causes the metric to be infinity in this case, 16 , the network destination is considered unreachable. Of course, this makes it impossible for RIP to scale to large or very large internetworks.

Note: The count-to-infinity problem is the reason why the maximum hop count of RIP for IP internetworks is set to 15 16 for unreachable. You can use this option for configuring the logs.
