Chapter 11: Configuring the SSR for IPX Routes
148 CoreWatch User’s Guide
The SSR uses IPX RIP to create and maintain a database of internetwork routing
information. The SSR's implementation of RIP allows the following exchanges of
information:
• Workstations locate the fastest route to a network number by broadcasting a route
request.
• Routers request routing information from other routers to update their own internal
tables by broadcasting a route request.
• Routers respond to route requests from workstations and other routers.
• Routers perform periodic broadcasts to make sure that all other routers are aware of
the internetwork configuration.
• Routers perform broadcasting whenever they detect a change in the internetwork
configurations.
SSR’s RIP implementation follows the guidelines given in Novell's IPX RIP and SAP
Router Specification Version 1.30 document.
On the SSR, RIP automatically runs on all IPX interfaces. The SSR will keep multiple
routes to the same network having the lowest ticks and hop count. Static routes can be
configured on the SSR using the CLI’s ipx add route command. Through the use of RIP
filters, the SSR can control the acceptance and advertisement of networks per interface.
When creating or modifying interfaces, you should realize that interfaces bound to a
single port go down when the port goes down but interfaces bound to a VLAN remain up
as long as at least one port in that VLAN remains active. The following table summarizes
this:
Each IPX interface can be bound to a MAC address as discussed in the SmartSwitch Router
Command Line Interface Reference Manual. Binding an interface to a MAC address is
optional. If an interface is not bound to a MAC address, the interface uses the system
address.
If Then
The port of a port-bound interface goes
down The interface bound to that port also goes
down
At least one port of a VLAN remains
active The interface bound to the VLAN remains
active
All the ports of a VLAN go down The interface bound to the VLAN also
goes down
