A static route is a RIP route that is added to a router's Routing Information Table by a network administrator rather than by the active routing protocol---in this case, RIP---operating over a network link. With Novell Internet Access Server 4.1, you can configure static routes and services for both permanent and on-demand calls.
A permanent call is a connection that remains active between the local router and the remote router identified by the call destination. An on-demand call is a point-to-point connection between two routers that becomes active only when one router must send user data to the router at the other end. On-demand calls are well-suited for connections that use expensive telecommunications carriers and for slow links over which it is undesirable to send routing and service traffic. For more information about permanent and on-demand calls, refer to Call Types.
You can configure static routes and services with the following utilities:
NIASCFG ---With NIASCFG, you must configure all routes and services manually. To activate the configuration on both routers, you select Reinitialize System from the Internetworking Configuration menu. Use NIASCFG to set up WAN call destinations at each end of the connection and configure static routes and services.
STATICON ---The static route and service configuration utility for IPX. STATICON uses the Simple Network Management Protocol (SNMP) to discover which routes and services are available through a remote router and adds them to the static routing table on a local router. Before configuring static routes and services with STATICON, you must use NIASCFG to set up the WAN call destinations and activate the configuration by selecting Reinitialize System . You then load STATICON and configure the static routes and services on the routers. STATICON configures all routes and services on each router automatically and allows you to try the static configuration before saving it to disk. The STATICON configuration becomes active immediately; you do not need to reinitialize or restart the router.
For more information about static routes and services and related topics, refer to Static Routes and Services.
This section contains the following topics:
NOTE: If you plan to configure static routing information, we recommend using STATICON to avoid potential routing loops.
Before you configure static routes and services with NIASCFG, determine the addresses of the networks or hosts that you want to access. Then set up a WAN call destination, on each router, to the router at the other end of the connection.
WARNING: When setting up a call destination, be sure you set the Remote System ID parameter to the server name of the system initiating the inbound call. The local system checks each inbound call against the remote system ID.
To configure static routes with NIASCFG, complete the following steps:
Load NIASCFG, then select the following parameter path:
Select Configure NIAS > Protocols and Routing > Bindings > a WAN interface > WAN Call Destinations.
Select a WAN call destination from the list, or press Ins to choose from a list of available call destinations.

STATICON provides a fast and error-free way to configure static routes and services on routers at each end of a point-to-point WAN connection. However, before loading STATICON, you must use NIASCFG to complete the following preparatory tasks on each router:
IMPORTANT: For STATICON to operate, the router at the other end of the connection must either be running Novell Internet Access Server 4.1 or be a third-party router that supports IPX SNMP and the IPX Management Information Base (MIB) variables.
When you load STATICON, the Select Configuration Method menu appears. Table 3 describes each menu option.
Table 3. Select Configuration Method Menu Options
Menu Option | Description |
---|---|
Dynamically Configure Static Routing Tables |
Opens an on-demand call to the remote router and allows you to edit the local and remote configurations using dynamically obtained selection lists. |
Configure Services from Gatekeepers |
Opens an on-demand call to obtain a list of services available from a gatekeeper and allows you to select the services you want. The gatekeeper is normally on the other side of a WAN link. |
Configure Local Static Services |
Lets you configure static services manually on the local router. This configuration is nearly identical to the one presented in Configuring Static Services. |
Configure Local Static Routes |
Lets you configure static routes manually on the local router. This configuration is nearly identical to the one presented in Configuring Static Routes. |
Write Static Routing Tables to Permanent Storage |
Sends IPX SNMP requests to the local router to put the routing table information into permanent storage. The router is polled to ensure that the information is updated. |
Restore Static Routing Tables from Permanent Storage |
Sends IPX SNMP requests to the local router to restore routing table information from permanent storage. The router is polled to ensure that the information is updated. |
The most efficient way to configure static routes and services is to select the Dynamically Configure Static Routing Tables option. This enables you to select from the following options:
For more information about configuring static routes and services dynamically, refer to Selectively Configuring Static Routes and Services and Automatically Configuring Static Routes and Services.
For STATICON to configure a remote router's routing and service tables, it must support IPX SNMP and the IPX MIB variables and have SNMP-write access to the router. If the remote router is running Novell Internet Access Server 4.1, specifying a Control Community from NIASCFG enables write access.
To check write access, complete the following steps:
Load NIASCFG on the remote router, then select the following parameter path:
Select Configure NIAS > Protocols and Routing > Manage Configuration > Configure SNMP Parameters
The Control State field should read Any Community May Write or Specified Community May Write . If it reads Specified Community May Write , note the name in the Control Community field. Use this name when you must provide the name of the SNMP control community in Step 8 of Selectively Configuring Static Routes and Services and Step 8 of Automatically Configuring Static Routes and Services.
Press Esc to return to the Internetworking Configuration menu.
Exit NIASCFG.
Through selective configuration, you can choose specific routes and services you want to add to a routing table. This feature lets you select from an existing routing table the routes and services that your router does not have in its table. You can copy routes to a remote router from a local router, or copy routes to a local router from a remote router.
To selectively configure static routes and services, complete the following steps:
Load STATICON.
Select Dynamically Configure Static Routing Tables .
STATICON displays the on-demand calls of which IPX is currently aware. It also shows the connection state of each call.
NOTE: The Auto Static Route listed in the display is the nonconfigured static route to the internal network on the other side of the WAN link. This automatic static route ensures a route across the link in case normal RIP filtering might prevent such a route. It must not be deleted.
Use the arrow keys on your keyboard to select the WAN call destination associated with the remote router.
If the Status field associated with the call reads Not Connected , press Ins to connect the call.
Wait for the Status field to change to Connected .
This can take several seconds if you are using a dial-up line.
