Demand-Dial Interface
|
RRAS in Windows Server 2008 enables you to create demand-dial interfaces. This is a logical interface representing a point-to-point connection, either a physical connection such as two routers connected with an analog phone line, or a logical connection such as teo routers using a VPN connection. It typically requires an authentication process when connection is being established. Two types of demand dial connections are available

Dynamic Route
|
dynamic route A route that is dynamically calculated and created on a RRAS
server acting as a router. (Poulton, 2012 cd. glossary) |
|
|
Hop
|
This is a step by taken by a packet from one router to the next one as it travels across the network. You could compare this to a flying one from one city to another. A direct flight would be a single hop, but if you need to change plans en route, you flight has two hops, and so on. The total number of hops is often called the hop count.

IGMP Proxy
|
As already mentioned, you can use a RRAS server to forward multicast traffic to groups of computers. In doing so, RRAS uses IGMP as an IP routing protocol component. IP multicasting operates by sending messages to a group that is identified by an IP multicast address in the class D range such as the224.0.0.9 destination mentioned earlier in this chapter. Destination hosts inform a local router to join the group.

Metric
|
An indication of the cost of using a route, typically the number of hops to the IP address
(Poulton, 2012 p.137) |
|
|
Packet Filter
|
IP packet filtering enables you to specify the types of traffic that can use the connection specified on the router. The filter enables you to specify the ports and protocols that are allowed or denied passage across the router. Use the following procedure to add a packet filter.

Persistent Route
|
Represents static routes that have been added to the routing table. More about persistent routes later in this chapter.

|
|
Router
|
router A device that operates at Layer 3 of the OSI protocol stack and manages
the flow of data between network segments or subnets. RRAS in Windows Server 2008 is capable of acting as a completely functional router on small to medium-sized networks. (Poulton, 2012 cd. glossary) |
|
|
Routing Algorithm
|
routing algorithm A mathematical algorithm that calculates optimal routes for
packets traversing an internetwork. Such algorithms take many factors into consideration, including the speed, bandwidth, availability, and cost of each link. (Poulton, 2012 cd. glossary) |
|
|
RIP
|
Routing Information Protocol
Windows Server 2008 uses Routing Information Protocol (RIP, also sometimes known as Routing Information Protocol) is exchanging information among routers in an internetwork. The purpose of a routing protocol is to facilitate the capability of routers to automatically adjust network paths according to network conditions such as overuse or failure of a given network connection. (Poulton, 2012 p.133) RIP is a distance-vector routing protocol that is simple to configure and deploy on networks of various sizes. In distance-vector routing protocol, every router communicates the routes it knows about to all neighboring routers to which it is directly connected. These neighboring routers then broadcast the changes to their neighbors, and so on. (Poulton, 2012 p.134) |

Routing Table
|
The routing table is a complete description of all the routes available from any computer, not just a server configuring for routing. You can view the routing table by executing the route print command from a command prompt.
(Poulton, 2012 p.134-135) (Poulton, 2012 p.135-136) |
|
|
Static Route
|
IN some cases you might want to add a static route ti your Windows Server 2008 router. Doing so ensures that the router knows about a specific network, including the address of the gateway servicing as the next hop, and the interface to which it should forward packets and being sent to the network. You can either use the RRAS snap in or the rout command to create a static route.
