RE: RFC1483 Bridging

I am sorry I missed the FastEthernet interface. Why are you not using this
as the DSL router instead of the modem if you have the ATM interface? I
must be really out of it today to have missed these things.

 

Here is a sample configuration for configuring the router as a DSL router.

HiTyson,
 
PVC is terminating on to Modem Which sits inbetween 1841 and DSLAM
 
Do you have the sample configs or any documents that talks about this. I
will be interested in knowing this in bit detail.
 
Thanks and Regards
Arun
