  • Page 35: Chapter 4. Applications

    This chapter provides examples of some common FSU applica- tions. The examples include SNA/SDLC with local spoofing, SNMP/Telnet management, bisync point-to-point and multi- point, and transparent applications. The configuration selections given in these examples may need modification based on your network configuration.

  • Page 36: Figure 4-1 Sna/Sdlc With Local Spoofing

    Chapter 4. Applications In all cases, the FSU is transparent to the XID (exchange identifica- tion) negotiation between any two network devices. The FSU uses LLC protocol (mode 2) to transport SDLC informa- tion frames. This protocol ensures a reliable link across frame relay, providing protection from frame loss and excessive delays.

    IP ROUTING WITH THE FSU The FSU contains an IP router function to resolve paths for IP packets received. This function is used regardless of encapsula- tion protocol and port received from. The heart of the routing system is a routing table which can be generated manually, automatically, or a combination of the two.

  • Page 92: Figure 8-1 Vt 100 Ip Route Menu

    Chapter 8. IP Routing The FSU can also respond to requests from peer routers/FRADs seeking an association for their tables. The transmit and receive inverse ARP section can be independently enabled. Access IP Routing selections by first choosing 1 CONFIGURA- TION from the Main menu.

  • Page 93: Figure 8-2 Ip Routing Table Menu

    IP Route Table Use these menu options to build a table of addresses for routing data packets based on their IP address. When a packet with the specified IP address is received, it is sent out through the se- lected port on the specified DLCI. See Figure 8-2. The IP route table can be used in conjunction with RIP protocol to provide routing paths for the entire IP network.

  • Page 94: Example Route Table Entry

    Chapter 8. IP Routing Example Route Table Entry IP Address=192.239.232.0 Destination Port=Network Port Destination DLCI=16 This example provides a route for IP address range 192.239.232.1 through 192.239.232.254 using the network port and virtual circuit 16. See the following parameter descriptions. IP Address (IP ADDR) Enter the IP address to be routed.

  • Page 95: Gateway Ip Address (Gw Ip Add)

    Gateway IP Address (GW IP ADD) Enter the Gateway IP address. If an IP packet with an unknown IP address is received, the FSU sends it to the Gateway (which is a router or another FRAD). Gateway Port (GW PORT) Enter the port from which the gateway can be reached.

  • Page 132 Glossary bridge A device that supports LAN-to-LAN communications. Bridges may be equipped to provide frame relay support to the LAN devices they serve. A frame relay capable bridge encapsulates LAN frames in frame relay frames and feeds them to a frame relay switch for transmission across the network. A frame relay capable bridge also receives frame relay frames from the network, strips the frame relay frame off each LAN frame, and passes the LAN frame on to the end device.
  • Page 133 Cyclic redundancy check. A computational means to ensure the accuracy of frames transmitted between devices in a frame relay network. The mathematical function is computed, before the frame is transmitted, at the originating device. Its numerical value is computed based on the content of the frame.
