Hi!


Need you guys expert opinion on how to configure configuring CE-PE link on Frame Relay over ATM. I am stump by this one because I never done it before. The CE is a Cisco 7206 with ATM PA and the parameters given to us is DLCI number in x/y format...isn't that the format for PVC. When asked, my SP contact says that it is indeed FR over ATM. Any of you guys who have experience to guide on this or point me in the right direction is most welcome. Thanks

Hello Helme,

ask your provider if they are doing FR to ATM service interworking.

In that case one side is configured for Frame-Relay and the other side for ATM

Service interworking is done by provider.


Verify that you have the same MTU on both sides and configure following ISP specifications


ATM uses two numbers to identify a PVC


int atm 4/0

no ip address

no shut

int atm 4/0.1 point-to-point

mtu 1500

ip address x.x.x.1 255.255.255.252

pvc x/y

enc aal5snap

protocol ip x.x.x.2 broadcast


this should be enough to have it working


on the other side configure or have a point-to-point subif configured on FR


see this example
