Thor, thank you for your answer.
Maybe, I had to specify more.
In the case:
Point-to-multipoint subinterface.
Inverse-arp has to be disabled for entire scenario.
Is it only needed in the subinterface?
Thanks again.

Asunto: Re: no frame-relay inverse-arp
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.

Hi again group,
Maybe this is a stupid question, but here I go:
When we are required to disable frame-relay inverse-arp, and we are working
with sub-interfaces, where we have to configure "no frame-relay inverse-arp"?
Below the main interface?
Interface serial 0/0
no ip address
encapsulation frame-relay
no frame-relay inverse-arp
Below the sub-interface?
Interface serial 0/0
no ip address
encapsulation frame-relay
Interface serial 0/0.1 point-to...
Ip address x.x.x.x x.x.x.x
no frame-relay inverse-arp
Both?
Many thanks for your answers. Can anybody to link me to a Cisco Doc about
this?
Manuel.
