Is r1 the hub and r2 and r3 are the spokes? If yes, are you running any dynamic routing protocols? If no, you need a static route from r2 poining to r1 and also static route from r3 pointing to r1.

Reza,


That is correct R1 is Hub r2 and r3 are the spokes.. no dynamic routing protocols ..


R2(config)#ip route 172.12.123.2 255.255.255.0 172.12.123.1

%Inconsistent address and mask



R3(config)#ip route 172.12.123.3 255.255.255.0 172.12.123.1

%Inconsistent address and mask



I tried that and I get and error


Thanks Resa

correction


You need to point to the network not to the host

Hi,


Are you using frame-relay inverse-arp betwen hub and spoke?.


If you use frame relay inverse-arp, try static host entry as below,



R2:


ip route 172.12.123.3 255.255.255.255 172.12.123.1


R3:

ip route 172.12.123.2 255.255.255.255 172.12.123.1


If you have static mapping, configure mapping for spoke pointing to your hub DLCI as below,


R2:

interface

frame-relay map ip 172.12.123.1 broadcast

frame-relay map ip 172.12.123.3


R3:

frame-relay map ip 172.12.123.1 broadcast

frame-relay map ip 172.12.123.2



If it doesnt work, Please post the config @ hub and spoke routers as well.


HTH,

Nagendra
