RE: AToM FR-Ethernet Interworking problem

As Bryan said, you need to bridge your traffic in R4. Or you can change to routed mode and it should work.

Also, it seems in some IOS releases we need to manually configure the dlci as switched. In other IOS releases, this is automatic.

Hi Rin,

Looks like you are doing bridged mode so I believe you will need "frame-relay map bridge" on the CE (R4). Also, I have this working
without specifying a switched DLCI on the PE (R1). What reference are you using?
