10. tunneling over TCP IP Internet IPEX IPEX lets you send and receive messages between two X 25 systems via a TCP IP network The tunneling maps TCP sockets to X 25 virtual circuits IPEX works with X 25 switched virtual circuits SVCs as well as with TCP IP protocols over all interface types that Bay Networks routers support For further information about IPEX refer to Configuring X 25 Services X 25 Support for RFC 1356 RFC 1356 defines a standard for multiprotocol encapsulation over X 25 networks Bay Networks implements RFC 1356 for IP OSI IPX DECnet and XNS This means you can use Bay Networks routers at one end of a connection and equipment from another vendor that also supports RFC 1356 for these protocols at the other end of the connection For further information about RFC 1356 refer to Configuring X 25 Services The following features are new in 11 0 for IP services RIP Support for Dial Optimized Routing Dial optimized routing DOR reduces costs on dialed lines Under DOR RIP exchanges routing information on the interface only when the router or a peer has activated the connection for a data transmission RIP does not initiate a connection on a dialed line just to issue a routing update unless it is the first time the dial line is initialized For information on configuring a RIP interface for DOR see Configuring IP Services Chapter 4 114093 Rev A Release Notes for Router Software Version 11 0 IP Acco

13. No default priority queuing filters exist for IPX diagnostics packets or packets used in NDS time synchronization You can configure a priority queueing filter to keep IPX diagnostic packets from bringing up a demand line However since the Bay Networks IPX ping packet is a diagnostic packet the filter will affect it as well NDS time synchronization packets are treated as data packets You can configure NetWare servers for larger polling intervals to reduce the frequency of bringing up the line for time synchronization packets 114093 Rev A 15 Release Notes for Router Software Version 11 0 Using Frame Relay Service Records The following sections compare service records to the access modes that formerly defined Bay Networks Frame Relay services Group Access Mode In group access mode upper layer protocols treat each Frame Relay network interface as a single access point to the switched network The upper layer protocols use a single network address to send all traffic destined for the switched network to the Frame Relay network interface When you configure each router you assign only one network address for example an IP or IPX address to the Frame Relay interface not to each PVC The DLCMI dynamically configures PVCs you do not need to explicitly configure them Group access mode advantages are that it e Supports all protocols e Simplifies network addressing because you define and associate only one protocol address
