disable frame-relay inverse-arp when you don't want the router to
dynamically ask another router for it's L2/L3 mapping ie if you want to use
static mappings that you need to define. if you have R1, R2 & R3 in a full
mesh but you don't want to use the vc between R2-R3, then by default you
will inverse-arp for the address of R3 from R2. in this situation, disable
frame-relay inverse-arp, clear frame-relay inarp & then apply you manual
frame-relay map statements to manually direct the traffic & which
frame-relay pvc you should use. BTW you can't disable a router replying to
frame-relay inverse-arp messages, you can only disable a router asking for
them.
you can't disable frame-relay inverse-arp on a point-to-point link but for a
good reason, you only have 1 PVC that you will send the traffic to ie the
host at the other end.
