connection is up, network traffic passing across the link causes the inactivity timer for the link to be reset, keeping the connection up.
The IPX RIP protocol periodically sends out update information across a link. These periodic update packets will cause a WAN interface set for
•If Triggered is selected with this

RIP Update Timer
This value dictates how often the device sends out IPX RIP (Routing Infor- mation Protocol) packets on the WAN link attached to this interface. The RIP packets sent out on this interface contain information about networks for which this device is responsible. RIP packets received tell the device about other networks and routers. The default is 60 seconds.
SAP Update Timer
This value dictates how often the device sends out IPX SAP (Service Access Protocol) packets on the WAN link attached to this interface. The SAP packets sent out on this interface contain information about services (such as servers, printers, etc.) for which this device is responsible. SAP packets received tell this device about services available on other network segments. The default is 60 seconds.
Optional Remote Node Network Number
Besides defining a method for
If remote node operation is desired, the WAN interface would usually be set up as an unnumbered interface, and the Remote Node Network Number would then be set to an IPX network number from the router’s Ethernet interface(s).
Alternatively, if the interface is set to be numbered, an unused IPX network number may be used.
