ATM issue between CE and PE

[enriquebs]

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.

[lgijssel]

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...
