Athena IP Router Configuration Procedures

Article Number: H010
Article Type: HowTo
Modified: March 26, 1999

SUMMARY

The Athena IP Router allows an Athena to operate in an IP-routed network, and inter-operate with other routers. The configuration and setup of the IP router within Athena is a multi-part process involving both the LAN interfaces and WAN interfaces. To simplify this process, the following article details the step-by-step process of activating the router functionality within the Athena.

MORE INFORMATION

This procedure is based upon a simple application. The diagram below depicts this application, and consists of two Athena nodes connected by way of a Frame Relay trunk. A workstation exists on both LANs as test stations, and both LANs have been assigned a unique IP network address.

Software Requirements

For Athena to support a LAN connection and IP routing the following binaries will need to be downloaded into the Athena:

  • IP Binary (ip100x.bin)
  • RWI Binary (rwi100x.bin)
  • LAN Binary (lan100x.bin)
  • Bridge Binary (brg200x.bin)

All Athena software can be found on our FTP Server.

Router Configuration in a Frame Relay Network

Node 1 - Configuring Node and Region ID

The region and node IDs may both range between 1-199. Each Athena in a contiguous network must have a unique region and node ID combination. In our example the Athena node and region ID's are as follows:

  • Athena region 1 node 1.
  • Athena region 1 node 2.

To configure the Athena's node and region ID enter the following command from the Root Command Menu:

  1. Type co nm ni 1, then press [enter].
  2. Type ri 1, then press [enter].
  3. Type q, then press [enter] to go back to the Config Command Menu.

Node 1 - Configuring the LAN and WAN IP Links

This procedure will connect the IP router over a frame relay trunk.

  1. Type lr wa fr, then press [enter] to get to the Router WAN Interface Frame Relay Command Menu
  2. Type ed node2, then press [enter] to create a link group name.

    The Router WAN Interface Edit DLCI Command Menu and its frame relay configuration options will be presented.

  3. Type dl 16, then press [enter] to set the local DLCI number.
  4. Type tr 2, then press [enter] to set the destination trunk. If proprietary network trunks or bridge DLCI's are being used then follow steps 5 to 8.
  5. Type tr rwi, then press [Enter]. Exit trunk is the router wan interface.
  6. Type ri 1, then press [Enter]. Remote node Region ID.
  7. Type ni 2, then press [Enter]. Remote node Node ID.
  8. Type dd 16, then press [Enter]. DLCI of remote router.
  9. Type dd 140, then press [enter] to set the destination DLCI.
  10. Type ci 64000, then press [enter] to set CIR of router.
  11. Type dc 0, then press [Enter] to disable destination sub-channel. Unless FRF11 DLCI is being used this feature should be disabled.
  12. Type fr en, then press [Enter]. If disabled, any frames longer than configured frame length will be discarded.
  13. Type q q q, then press [enter] to go back to LAN/WAN Router Command Menu.
  14. Type ip li, then press [enter] to go to IP Links Command Menu.
  15. Type ed 1, then press [enter] to configure the LAN link to the router.
  16. Type ct lan (trunk number of LAN card), then press [enter] to set the connection type. For example, if the LAN carrier module is connected to the CPU in the first slot than the trunk number is 5.
  17. Type ms 24, then press [Enter]. IP mask for Node 1.
  18. Type la 212.212.212.200, then press [Enter]. IP address for Node 1.
  19. Type q, to save the link configuration. You have now made a link between the physical Ethernet port and the IP Router.
  20. Type sh, to show the link connection. The state of the connection should be in link up state.
  21. Type ed 2, then press [enter] to configure the WAN link to router.
  22. Type ct wan node2, then press [enter] for connection type.
  23. Type ty un, then press [enter] for type of connection. In our example, we are using unnumbered type connections.

    Note: The Athena router also supports numbered type connections.

  24. Type ms 16, then press [enter] for mask size of remote node.
  25. Type pa 132.147.160.200, then press [enter] for peer address (IP address of remote node).
  26. Type q, then press [enter] to save link configuration. You have now created a link between the WAN port and the IP router.
  27. Type sh to see the link connection. The state of the connection should be in link down state.
  28. Type q, then press [ENTER] to get to the Lan Router IP Command Menu
  29. Type lo, then press [ENTER] to get to the IP Local Level Command Menu
  30. Type sh, to display configuration. Ensure Nonstandard Subnets and Proxy ARP is disabled. These features are not required in a basic IP router setup.
  31. To disable Nonstandard Subnets, type ns di [ENTER].
  32. To disable Proxy Arp, type pa di [ENTER].
  33. Ensure IP Address and Mask agree with IP link 1. See steps 17 and 18.
  34. Type q q q, then press [enter] to get to the Config Command Menu.
  35. Type tr 2 dl, then press [enter] to get to the Frame Relay DLCI Command Menu.
  36. Type ed 140 ci 64000 de 1 1 rw 16, then press [enter]. This tells the Athena that DLCI 140 on port 2 connects to DLCI 16 on the Frame Relay Router. Enter sh, to display the DLCI configuration. The assumption has been made that the Frame Relay link is up between Athena's. If proprietary network trunks are being used, do not follow this step. If a Bridge DLCI is being used than DLCI will have no destination.
  37. Type q q q q, then press [enter] to go back to the Root Command Menu. Before getting to this menu the NMP will display the following prompt, 
    WARNING:
Quitting will cause configuration changes you made to save to disk!
Do you wish to continue? (y/n)
    Type y, to save changes.
