Frame-Relay Mapping palaver

Hello,

Please i need help with my FR-Mappings. Which is designed as follows:

R1, R2 and R4 connected together over frame-relay configured as multipoint on their respective subinterfaces, i chose this because R1 and R2 still have another point-t-point to other routers (R3 AND R5) which works fine.

Though the multipoints of the 3 routers (1, 2 and 4) works fine too but generates unwanted mapping to unsed PVCs.

I am totally confused because i have disabled "inverse-arp" on both the main and the sub-interfaces of these routers.

Here is the outputs of (R1, 2, and 4) that post problems. I guess i don't have to paste the gibberish output of the unwanted PVCs here.

Thank you all as usual.

Re: Frame-Relay Mapping palaver

Hello New,

try to add

no arp frame-relay on serial interfaces

then wait at least 60 seconds and redo sh frame-rel pvc

Can you ping 10.124.1.4 from R2 ?

Hope to help

Re: Frame-Relay Mapping palaver

Keep this in mind, no frame-relay inverse-arp disables the reply, not the request - thus if you have a remote router without no frame-relay inverse-arp, this router will respond to your requests.

If all routers have no frame-relay inverse-arp in the frame-relay cloud and the mappings remain, try rebooting all routers.

Frame-relay, at times, can become hairy and reboot seems to fix it 9/10 times.

HTH,
