Routing with Windows Server 2003

 Q.       What is routing? Explain how to use the routing and remote access feature in WINDOWS SERVER 2003?

 

Understanding Routing

• Routing is the process of transferring data across an internetwork from one local area network (LAN) to another.
• Routers, which operate at the third, or network layer of the OSI model, are known as “layer 3” devices. In IP networks, routing is performed according to IP routing tables.
• All IP hosts use routing tables to forward IP traffic; IP routers are distinctive from hosts in that they can use these routing tables to forward traffic that has been received from another router or host.

 Using Routing And Remote Access

• The Routing And Remote Access service in Windows Server 2003 is a multiprotocol software router that can be readily integrated with Windows features such as security accounts and group policies.
• The service can be configured for LAN-to-LAN, LAN-to-WAN, virtual private network (VPN), and Network Address Translation (NAT) routing through IP networks. In addition, the service can be configured for routing features such as IP multicasting, demand-dial routing, DHCP relay, and packet filtering.
• Finally, it offers built-in support for the dynamic routing protocols Routing Information Protocol (RIP) version 2 and Open Shortest Path First (OSPF).
• Hardware routers include many built-in ports, each of which typically connects to a distinct network segment.
• For Routing And Remote Access, however, the number of network segments among which traffic can be routed is limited by the number of network interfaces installed on the Windows Server 2003 computer running the service.
• Figure below illustrates an example of a Windows Server 2003 computer running the Routing And Remote Access service and configured with four network adapters. In this scenario, the Routing And Remote Access service is routing IP traffic among four LANs.
