Thanks for all who replied. Tricky problem! Looks like the problem is with
Split-horizon and using mac address of actual node. I revised it to :
ipx sap 4 fileserver 222.0000.0000.0001 0 2
and that does the work. Eventhough the static sap entry was made and
network 100 is frame-relay, I guess R2 does not want to advertise that
network out of 100 since that is where the static is pointing to. I'm not
sure if this is considered Split horizon problem or not as R2 never heard
this SAP entry from IPX 100 network. I guess creating a static SAP entry is
the same as hearing from Network 100. I ended up creating a bogus network
of 222 using loopback0 and also use bogus mac address...

Definitely be aware of the direction and split horizon issues, but also take
note that your syntax for the ipx sap command is a little different that
what you would think it would be... Don't use the actual mac address of the
node. Also, the sap should be advertised as 2 hops away.
Mentor labs V-labs for IPX contain many examples of static sap's as that is
how they simulate Novell Servers in their scenario's. Check out the vlab
entitled "1013. Configuring an IPX Network With Access Lists".
Here is an example of some static sap entries done correctly:
ipx sap 4 fileserver 100.0000.0000.0001 0 2
ipx sap 7 printserver 100.0000.0000.0001 0 2
ipx sap 107 rconsolecon 100.0000.0000.0001 0 2
HTH.
