frame relay

[cisco steps]

since I reconfiguring frame realy switch ..

R1 can ping r2 and r3

R2 can ping r1

r3 can ping r1

r2 can not ping r3

r3 can not ping r2

frame-switch#sho frame-relay route

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

You need to point to the network no to the hose like:

ip route 172.12.123.0 255.255.255.0 172.12.123.1

I attached an example for your routers

correction

You need to point to the network not to the host

[cisco steps]

still not working RESA,

here is my topology, i went to r2 and added

ip route 172.12.123.0 255.255.255.0 172.12.123.1

and on r3

ip route 172.12.123.0 255.255.255.0 172.12.123.1

am I doing something wrong . is my frame relay config correct...

Thanks

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
