Presentation Transcript

  1. Chapter 5: Multiprotocol Routing Designs • Designs That Include Multiprotocol Routers • IPX Routing Design Concepts • AppleTalk Routing Design Concepts

  2. IPX and AppleTalk Routing • Microsoft Windows 2000 supports Internetwork Packet Exchange (IPX) and AppleTalk routing. • Multiprotocol devices can support IPX and AppleTalk. • Devices must support host routing.

  3. Multiprotocol Routing Design Review • Amount and confidentiality of data • Network growth plans • Existing routers, connections, and protocols • Application response times • Availability and reliability

  4. Routing Design Decisions • Types of connections • Connection technologies • Dynamic routing protocol vs. static routing table • Multiple routers and route paths • Packet filters • Authentication and encryption

  5. Edge of Network Scenario

  6. IPX Tunneling Scenario

  7. Placing Routers • Review organizational needs. • Position at the edge of the network or within the private network. • Use low cost hardware routers for internal routing.

  8. Integrating Routers • Specify • IPX network number and frame type • Type of connection • Multiple IPX frame types • Router interface connection and persistence

  9. Internal IPX Network Numbers • Assign numbers for applications and services. • Create unique numbers. • Create a meaningful numbering scheme.

  10. IPX Routing Table Management • Static routing entries • Routing Information Protocol for IPX (RIPX) • Autostatic RIPX

  11. Service Advertising Protocol (SAP) • Advertises available applications and services • Uses tables • Broadcasts to IPX network segments • Propagates throughout network

  12. Managing SAP Traffic on Routers • Use static SAP entries. • Disable SAP forwarding. • Filter SAP forwarding. • Enable SAP forwarding. • Use autostatic SAP.

  13. NetBIOS over IPX • Forward all NetBIOS over IPX traffic. • Filter specific NetBIOS over IPX traffic. • Create static NetBIOS name entries. • Disable NetBIOS over IPX traffic.

  14. Protecting IPX Traffic • Protect data in IPX over IP tunnels. • Specify listen only, advertise only, or both, for RIPX and SAP traffic. • Use • IPX filters • RIPX filters • SAP filters

  15. Optimizing IPX Routing • Increase availability and performance. • Review the organization’s requirements. • Deploy redundant routers and connections, and balance loads. • Analyze routing table management.

  16. AppleTalk Router Design

  17. Determining AppleTalk Network Numbers • Assign a number to each segment. • Assign additional numbers for devices. • Assign numbers on EtherTalk and TokenTalk segments. • Create meaningful numbering schemes.

  18. Selecting AppleTalk Seed Routers • Seed routers are the source of network numbers and AppleTalk zones. • You must designate at least one seed router for each network segment.

  19. Optimizing AppleTalk Routing • Optimize for availability and performance. • Base decisions on organizational needs. • Make same design decisions as for IP routing.

  20. Chapter Summary • Windows 2000 support • IPX routing • AppleTalk routing
