Hi Pavel,

 

Thanks for your reply,

 

R2 send the arp and R1 have the mapping, but funny enough, I found R2 also
have the mapping to R1 and I have disable the frame-relay inverse-arp.

 

How can it be like this ?

 

I have do this in mock lab exam 1 and prove works. Just want to know behind
the technology.

If R2 SENDS the inARP, then R1 will RECEIVE it, and have the mapping.

R1 does not SEND in-ARP and therefore R2 does not RECEIVE it and should not
have the mapping.

Hi Shaughn,

That's right, R2 still sending it to R1, but in my understanding right now,
when R2 sending the inverse-arp, should be only R2 can automatically map the
R1 ip address right ? The question is how R1 map the R2 ip address cause as
you know I have disable the frame-relay inverse-arp on R1.

When you disable inverse arp you stop that router from sending it not
receiving it

So in your case although you had it disabled it on R1, R2 was still
sending it to R1.

You need to disable it on both.

Guys,

Just finished my mock lab exam 1 and just confuse with frame-relay
inverse-arp works.

if I Have topology

R1 s0/0 -----------s0/0 R2

So the question is :

When I have no frame-relay inverse-arp on s0/0 R1 but enable frame-relay
inverse-arp on R2, I'm really surprised why R1 s0/0 can have map the ip
of
R2 though I have disable the frame-relay inverse-arp, it supposed cannot
map
itself right ?

Can anyone explain how frame-relay inverse-arp work ?

Thanks guys
