Module 8: Configuring Routing by Using Routing and Remote Access
Overview • Multimedia: The Role of Routing in the Network Infrastructure • Enabling and Configuring the Routing and Remote Access Service • Configuring Packet Filters
Multimedia: The Role of Routing in the Network Infrastructure • The objective of this presentation is to provide a highlevel overview of routing in the network infrastructure • After this presentation, you will be able to: – Describe how routing fits into the network infrastructure – Explain the difference between local and remote routing – Describe how the Microsoft routing solution fits into the network infrastructure
Lesson: Enabling and Configuring the Routing and Remote Access Service • Overview of Routers • Defining Routing Interfaces • Using Routing Protocols • Configuring Routing Tables • Why Use the Windows Server 2003 Routing and Remote Access Service? • Practice: Enabling and Configuring the Routing and Remote Access Service
Overview of Routers A router is a multihomed device that can forward packets based on network addressing Subnet1 Subnet2 Subnet3 Subnet4 10.10.1.0/24 10.10.2.0/24 10.10.3.0/24 10.10.4.0/24 Router1 Router2 Router3 DEN-CL1 Subnet5 DEN-CL5 DEN-CL4 10.10.5.0/24
Defining Routing Interfaces A routing interface is a network connection over which packets are forwarded Two types of routing interfaces: LAN Demand dial
Using Routing Protocols A routing protocol is a set of messages that routers use to determine the appropriate path by which to forward data Is designed RIP for Is designed OSPF for small to medium large to very networks large networks Uses a routing Uses a link state table database Is easier to Is complex to configure configure and manage and manage Does not scale Operates well efficiently in large networks
Configuring Routing Tables A routing table contains information about the location of the network IDs in the internetwork Three types of routing table entries: Network route Host route Default route
Why Use Windows Server 2003 Routing and Remote Access Service? Windows Server 2003 Routing and Remote Access is a service that performs routing as one of its multiple processes Internal Remote Site Using Subnets Demand Dial L L A A Corporate N Corporate N Network Network Remote Remote Access Using VPN Site Tunnel Corporate Network
Practice: Enabling and Configuring the Routing and Remote Access Service In this practice, you will: Configure Routing and Remote Access for LAN routing Add a static routing table entry Configure a routing protocol
Lesson: Configuring Packet Filters • Using Packet Filtering • How Packet Filters Are Applied • Practice: Configuring Packet Filters
Using Packet Filtering Packet filtering prevents certain types of packets from being sent or received across a router Inbound Filter Route r Outbound Filter Use packet filtering to: Prevent access by unauthorized computers Prevent access to resources Improve network performance
How Packet Filters Are Applied Packe Route t r Inbound Exclusion Component Example Filter Example Component Source 192.168.0.48 Source Any network network Destination 192.168.0.32 Destination 192.168.0.32 network network UDP UDP Protocol Protocol Action: Drop How filters are applied: AND is used within a filter OR is used between filters
Practice: Configuring Packet Filters In this practice, you will configure packet filters
Lab: Configuring Routing by Using Routing and Remote Access In this lab, you will: Configure Routing and Remote Access Plan a routing topology
