Has anyone got PS/2 AIX to perform IP routing between Token-Ring and
Ethernet?  I have not been able to and here's my setup:

todd	      psfile	    psfile        
130.224.5.14  130.224.5.14--130.224.4.14  
          |   |		     |		  
          |   |	             |		  
        +-+---+-+            |		  
    MAU | Token |           (=========================)
        +-------+           Ethernet

Since psfile is connected to both Ethernet and Token-Ring networks, it
*should* be able to act as an IP router (as documented in the IBM TCP/IP
User's Guide).  

I've setup todd to use psfile as the default IP gw (router).  From todd,
I ping 130.224.5.14.  Psfile then sent did a RIP broadcast to 130.224.5.63
to find 130.224.4.14!  Psfile didn't know that the packet was being sent
to itself.  Often this would cause psfile's token-ring interface to stop
accepting rlogin's although it would respond to icmp echo requests.
