ATM advice

Hi,

I am trying to connect two routers back to back using an Enhance PA-ATM on each side.

Howver after configured, I am not able to ping to each other even though both interface and protocol are showing UP/UP. I had attached the result below.

Can anyone advise me on the error ?

Router A

interface ATM10/0/0

no ip address

no atm scrambling sts-stream

no atm scrambling cell-payload

!

interface ATM10/0/0.1 point-to-point

ip address 10.9.1.5 255.255.255.252

pvc 10/100

ubr 145000

oam retry 5 5 5

encapsulation aal5snap

After the pvc command you should enter in the IP address of the other router as such

Router A

pvc 10/100

protocol ip 10.9.1.6 broadcast

Router B

pvc 10/100

protocol ip 10.9.1.5 broadcast

The other thing I would do is under the physical interfaces would be to enable the atm scrambling because that is a good thing.
