The Routing and Remote Access service in Windows Server 2003 provides the same routing services as most dedicated hardware routers. The rule of thumb is that when you have a high-speed WAN connection, such as a T-1, that carries heavy traffic, hardware routers are preferable. |
These two sentences are from the book page 5-12, they are typical Microsoft theory. It can do the work but you can never rely on it. Suppose a company can’t afford T-1 connection and hardware router, it can’t afford Microsoft Server 2003 licenses normally.
The key points of today’s lesson are:
- Use the command router to print, add, delete and change the route table.
Metric is a number, which the router uses to evaluate routes to the same destination. - RIP (Router Information Protocol) is a distance vector routing protocol, metrics in distance vector routing protocols represent the number of hops to the destination.
- RIP uses broadcast or multicast to exchange route tables.
- OSPF (Open Shortest Path First) is a link state routing protocol, it metric criteria include the link’s transmission speed and delays caused by network traffic congestion.
- OSPF router compiles a map of the network called the link state database.
- To support IP multicasting, a router must support IGMP and have network interface adapters that support multicast promiscuous mode.
