I tried this in the lab and it worked like a charm!!!!!!!!!!!!!!!!!!!!!!!!
Check this out. Here are my four interfaces hanging off the Ethernet

interface Ethernet0.1
 ipx network 11
!
interface Ethernet0.2
 ipx network 12 encapsulation SAP
!
interface Ethernet0.3
 ipx network 13 encapsulation ARPA
!
interface Ethernet0.4
 ipx network 14 encapsulation SNAP

Here is my debug! Debug ipx sap events, debug ipx packet, debug ipx sap
activity.
IPXSAP: positing update to 13.ffff.ffff.ffff via Ethernet0.3 (broadcast)
(full)
IPXSAP: positing update to 11.ffff.ffff.ffff via Ethernet0.1 (broadcast)
(full)
IPX: Et0.3:12345.0050.0f01.1c60->12345.ffff.ffff.ffff ln= 96 tc=00, rcvd
IPX: Et0.3:12345.0050.0f01.1c60->12345.ffff.ffff.ffff ln= 96 tc=00, bad pkt
IPX: Et0.3:12345.0050.0f01.1c60->12345.ffff.ffff.ffff ln= 40 tc=00, rcvd
IPX: Et0.3:12345.0050.0f01.1c60->12345.ffff.ffff.ffff ln= 40 tc=00, bad pkt
IPXSAP: positing update to 14.ffff.ffff.ffff via Ethernet0.4 (broadcast)
(full)
IPXSAP: positing update to 12.ffff.ffff.ffff via Ethernet0.2 (broadcast)
(full)
IPXSAP: positing update to 13.ffff.ffff.ffff via Ethernet0.3
dcaend )

Look at e0.3. It has an error message with a network number of 12345. That
is the mystery network that I had my wife put in an adjacent router. Thank
you Ron, for the idea. If you look at my config, e0.3 has an encapsulation
of arpa. I deleted the subinterfaces and created a main interface that had
an encap of arpa. I then saw my saps come through the debug.
IPXSAP: positing update to 12345.ffff.ffff.ffff via Ethernet0 (broadcast)
(full)
IPXSAP: suppressing null update to 12345.ffff.ffff.ffff
IPXSAP: Response (in) type 0x2 len 96 src:12345.0050.0f01.1c60
dest:12345.ffff.ffff.ffff(452)
 type 0x4, "surf", 10.0010.0010.0010(451), 3 hops

The whole process took less than 10 minutes! Wooohooo!

where in the debug did you see the encap? I can't seem to find it?

What about "show ipx interface brief"

Asbjorn,

I know what you're getting at, but I wasn't able to figure out another way
of doing it. It's a pain in the butt and it definitely takes a bit of time
(and patience) to get the right IPX encapsulation and network #.
