	Not exactly.  More info needed.  Are you using a default *net*
route?  What about a default subnet route?  Are the routes that are
getting dropped subnet routes or net routes?  

	If the problem is with net routes, how many net routes are
there?  All the NSFnet or all the arpanet or both?  It is possible
that some router is overloaded and is not sending out routing updates
sufficiently often.  This is particularly likely with gated routers,
since the RIP process is a user process and routing is in the kernel.
We have been bitten by this when the gated router gets clogged with
traffic.  Look to the default net router and its interaction with the
external net router.

	If it is subnet routes getting dropped, make sure it isn't
something simple.  Make sure that subnets are being advertised
everywhere ["enable sending subnet routes" on all your subnetted
interfaces.] and that there is no default subnet (at least until you
fix the problem).  I apologize if this is so trivial that you have
already done all these things.  If it isn't something obvious like
this, then I can say I have never seen anything like that with subnet
routes before.  :-)

	BTW, what ever happened to the p4200 and info-proteon merger?
Is it like the CSnet/BITnet merger?  :-)
