ATM issue between CE and PE

HI all,

Here is the relevant config between a CE router and a PE router, the service provider says that the circuit is provisioned (sorry I don´t know the exact word, I want to say the ATM circuit is OK).

PE Router (7304):

vc-class atm 4M-IPoA

vbr-nrt 4000 4000 1

inarp 1

broadcast

oam-pvc manage 5

encapsulation aal5snap

interface ATM4/0

no ip address

atm sonet stm-1

no atm enable-ilmi-trap

no clns route-cache

!

interface ATM4/0.10 multipoint

description Conexion con PPAI Oviedo

ip address 10.9.142.1 255.255.252.0

no atm enable-ilmi-trap

pvc 6/76

class-vc 4M-IPoA

oam-pvc manage 5

!

!

CE Router (1721):

interface ATM0

no ip address

no atm ilmi-keepalive

dsl operating-mode auto

!

interface ATM0.1 multipoint

ip address 10.9.142.2 255.255.252.0

pvc 1/40

vbr-nrt 510 510

inarp 1

broadcast

oam-pvc manage 5

encapsulation aal5snap

!

Here is also some output information:

ATM4/0 unassigned YES manual up up

ATM4/0.10 10.9.142.1 YES manual down down

4/0.10 115 6 76 PVC SNAP VBR 4000 4000 1 DOWN

Thanks in advance,

One possible problem might be the pvc mismatch between PE & CE:

PE = pvc 6/76

CE = pvc 1/40

I don´t think so because each device has different VPI/VCI in order to get connectivity with the ATM switched network. They are not directly connected.

In that case you should verify that the ATM switch configuration is correct for these VP/VC pairs.

Yes, I agree with you, but the service provider who manage that switch says something like "all is OK here, check your config" and I think the config looks fine... the only thing I can do is contact again but I´m sure about the answer...
