dear all,
i have an issue concerned when i configure AToM to enable router to transport ATM aal5 between two PErouter
topology as below:
ATM ==PErouter1==MPLS-cloud==PErouter2== ATM
before I implement "mpls AToM" I configure it as:
=PErouter1=
interface ATM1/0/0
no shut
interface ATM1/0/0.1
pvc 0/164 l2transport
then i tried loopback testing for pvc (ping atm interface atm1/0/0.1 0 164 end). the test was okay (i got reply)
but when i put command :
int atm 1/0/0.1
pvc 0/164 l2
mpls l2transport route 172.30.248.32 610000
the pvc line between perouter1 and atm is down.
i tried ping atm interface atm1/0/0.1 0 164 end, the result is 'request timeout'
the same case is happened in both perouter.
sh mpls l2 vc
Local intf Local circuit Dest address VC ID Status

Hi Rano,
what hardware do you have (including core facing interfaces)?
Show LFIB of your PE routers. It would be nice if you show configs of both PE routers (interfaces: edge, core; mpls part etc).

Hi Alex,
i'm sorry i can't provide you anything about MPLS part, because that beyond my scope. but i can provide info about pe router config in attachment
cisco-PE1 = 6509
cisco-PE2 = 7609
and both are using card 4-subslot SPA Interface Processor-400
is there any problem with configuration or there are something that i missed it.
thx

I think the configuration is ok.
It seems you have a lan card as a core-facing interface.
ATM AAL5 over MPLS Restrictions
The following restrictionapplies to the ATM AAL5 over MPLS feature.
•Both CE-facing and core-facing cards must be WAN cards (enhanced OSMs, FLexWAN and Enhanced FlexWAN modules) and not LAN cards.
SUP720-PFC3B-based systems and SUP720-PFC3BXL-based systems require that the core-facing cards must be CWAN cards (enhanced OSMs, FlexWAN and Enhanced FlexWAN modules, and Shared Port Adapter [SPA] Interface Processors [SIPs]). This applies to CWAN-based Ethernet over MPLS, ATM AAL5 over MPLS, ATM Cell Relay over MPLS, and Frame Relay over MPLS.
hope this helps,
Alexander

thx a lot for the info lex,
i'm sure it is because of core-facing card too.
but do you have any solution for this issue, like upgrading IOS beside changing core-facing WAN interface, because it's gonna take lot of time to implement it (ordering, shipping, etc).
thx
