   Thanks Mike,
   I was following that story line and threw the config into
   the lab equipment last night. I created static saps while
   debug bugging ipx sap and kept getting the error that
   the route of my sap was not in the table. Sure enough,
   the ipx route of my sap origin lnterface was not in any of the routers
   that carried the 'rsup-only' command. Debug of ipx eigrp routing
   showed that route updates didn't even attempt to go out these
   'rsup-only' interfaces even though they were both part of the
   same ipx eigrp system. Without the route first being in the table,
   the sap will not be accepted.
   Caslows' book..page 511, says IPX EIGRP does not send out periodic
   updates of saps or routes unless a change occurs. However, on the one
   router with a static sap configured, I get the following meesage every
   60 seconds:
   router-5#
   IPXSAP: positing update to 50.ffff.ffff.ffff via Loopback0 (broadcast)

   IPXSAP: suppressing null update to 50.ffff.ffff.ffff

   the router config...
   !
   ipx router eigrp 1
   network 303
   network 50
   !
   !
   ipx router rip
   no network all
   !
   !
   ipx sap 0 server 50.0000.0000.0001 4 5
   Do you see any problems here??? Why is it still sapping?
