IPX Configuration 133
By importing routes, different routing protocols can share their routing
information. Note that IPX RIP imports only active static routes; inactive static
routes are neither imported nor forwarded.
Configuring IPX SAP Enabling IPX SAP
After IPX is enabled on VLAN interfaces, the system enables SAP automatically.
You can configure SAP parameters and service information as needed.
Configuring IPX SAP
In a large network, one IPX SAP broadcast consumes enormous bandwidth
resources. By configuring an appropriate SAP update interval, you can reduce the
bandwidth waste. Make sure that all servers and switches on the network have
the same SAP update interval to avoid the situation where the switches mistake an
operating server for a failed one.
The aging period of IPX SAP is a multiple of the IPX RIP update interval. You can
set multiple update intervals as an aging period.
