Frame-relay over isdn

[kanwaljeet]

I want to configure Frame-relay over isdn thru dialup. Can anyone guide me on this.

the scenario is as given below:

i have client at location A. location A is connected to location B on serial port using Lease line. Location B is connected to location C thru Lease line on serial port.Now location C is connected to location D over ATM backbone using Nortel passport 7480. The same client has location E which connects to location D with ISDN BRI at both ends. Location D dials into location E and establishes the connectivity. For the above scenario, i want to configure end to end FR. Location A is central location of client and location E is remote location of the client. location E wants to access location A over end to end FR network. We are able to configure end to end FR if the location D is connected to E thru Lease line on serial port but in this scenario the last mile connectivity is on ISDN BRI.

An early response will be highly appreciated.

Thanks in advance.

I'm not sure which router you have tried to get this to work with; I assume it's at location D. At any rate, this URL describes how to configure FR switching over ISDN, and hopefully it will be useful for you.
