Configuration for an ATM wan link - reg

we are trying to establish a STM1 link between New York and London. the port adapter we use is the pa-a3-oc3smi. we see the interface and protocol UP. but we are unable to ping the wan interfaces from both sides.

the configuration is as follows:

london:

interface atm4/0/0

ip address 203.195.x.y 255.255.255.252

atm sonet-stm1

no atm ilmi-keepalive

no atm enable-ilmi-trap

no ip directed-broadcast

atm pvc 1 1 5 aal5snap

New York:

interface atm4/0/0

ip address 203.195.x.z 255.255.255.252

no ip directed-broadcast

atm sonet-stm1

no atm enable-ilmi-trap

no atm ilmi-keepalive

atm pvc 1 1 5 aal5snap

Is the above configuration right for a point to point stm1 link terminating on the atm adapter? If any other configuration is missed?

Re: Configuration for an ATM wan link - reg

It would be advisable to use point-to-point sub-interfaces for your connection (in case you decide to build more PVCs later). In addition, try and use a VCI greater than or equal to 32. Try the following config:

london:

interface atm4/0/0

no ip address

atm sonet-stm1

no atm ilmi-keepalive

no atm enable-ilmi-trap

no ip directed-broadcast

!

interface atm4/0/0.1

ip address 203.195.x.y 255.255.255.252

pvc 1/32

encapsulation aal5snap

New York:

interface atm4/0/0

no ip directed-broadcast

atm sonet-stm1

no atm enable-ilmi-trap

no atm ilmi-keepalive

!

interface atm4/0/0.1

ip address 203.195.x.z 255.255.255.252

pvc 1/32

encapsulation aal5snap
