The issue with ISIS over frame-relay is with a point-to-point subinterface
to a multipoint subinterface or to a physical interface.
I just retested all this in my lab and confirmed what works and what doesn't
work.
Works:
1. point-to-point subinterface to a point-to-point subinterface
2. physical interface to a physical interface
3. mulitpoint subinterface to a multipoint subinterface
4. multipoint subinterface to a physical interface
Doesn't work:
1. point-to-point subinterface to a physical interface
2. point-to-point subinterface to a multipoint subinterface
Basically the issue is with point-to-point interfaces sending point-to-point
IIH's (ISIS hellos) and multipoint or physical interfaces sending LAN IIH's.
There isn't a way to change the hello types.
Also remember that if you're going to run ISIS over frame relay on a
multipoint subinterface or a physical interface you'll need to map clns to
the dlci.

I think the issue is that IS-IS doesn't have the 'tweaks'
for setting network types that OSPF does. (*Thank you ECP-1*).
Thus the interface must be either point to point or multipoint
in order for this to operate.
(If you need to run IS-IS across a link that's in this category,
use a tunnel)
