Stephen,
I have used "no frame-relay inverse-arp" on R4. This comand prevents inarp
REQUEST.
This is well-known behavior.
This command doesen't prevent inarp RESPONSE..
Check my debug in my previos post, please.
My question was "How disable inarp response?".
I tryed "no arp frame-relay" on R4, but with no success.
In my transcript, R4 has "no frame inverse-arp" and "no arp frame" ,
shutdown and enable interface (on both routers) and sitll R4 REPLIES inarp.
I even reloaded both routers. No success.
Of course the simplest way to disable inarp replies is disable inarp request
on peer router, but my question was how to disable inarp REPLIES on local
router".
Best regards
Marek
Best regards,
Marek
