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

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.

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

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

Edge of Network Scenario

IPX Tunneling Scenario

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.

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

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

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

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

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

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.

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

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

AppleTalk Router Design

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.

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.

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