The frame-relay route command tells the switch which DLCI to advertise on
the local interface, and onto which interface to switch received traffic for
that DLCI.
Inverse-ARP is doing the IP address to DLCI resolution for the routers on
each side of the frame-relay link. There are 3 ways to associate a DLCI with
layer 3 traffic on a Cisco router:
1. Inverse-ARP
2. frame-relay map statements
3. frame-relay interface-dlci statements
The Caslow book as a good description of when you need to use each, and what
happens when you combine methods.
I hope this helps.
