Let me just add something more:

I am not just connecting two routers in

point-to-point configuration. I want to connect several routers in a point-to-multipoint configuration using HDLC over

Hello Raoul,

I don't think you can use HDLC encapsulation in a point-to-multipoint scenario.

HDLC header even in Cisco HDLC version has no DLCI header and so what is the way to signal a frame is for device 2 and the other is for device 3 and so on ?

Or you send all frames to all routers but this is not efficient.

Ask to your provider if you can use FR encapsulation that is possible on a serial interface.

Hope to help
