923.0. "FEP-FEP connectivity with RouteAbout ???" by QCAV01::MUNISH () Tue Jun 03 1997 02:01

    Hi,
    	We have the following requirement for a customer in India.
    
    	In the IBM SNA environment, 2 FEPs need to be connected back to
    back via our RouteAbout family routers. From the SPD of DRSv2.0, we
    understand that it is not supported. But other vendors like Bay
    networks and Cisco claim that it is possible with their routers.
    
    	Can anyone tell us whether it is possible to connect the FEP-FEP
    via routeabout routers? If yes, how to go about it?

Not quite  sure what your asking for.  Unfortunatly I know zip-all about SNA
so have no idea what the FEPs do and how you plan to use the RAs.

If you want to connect two RAs "back-to-back", via a sync line, the only way
is  via  a modem eleminator; we don't support internal clocking & null modem
cables like most vendors.

    This could well be what we call 'SDLC relay'.  If you look in the SPD
    under that term, or in the SNA documentation (a whole book in the V2
    docset) you may find the information you are looking for.

    Hi,	
    	We need to connect the FEPs in different locations via RouteAbouts.
    	Basically , it means creating T4 to T4 links over the WAN. From the
        SPD, it is understood that this type of FID4 connections are NOT
        supported.
