Hello,


I am just wondering if this is possible.


If i can get a telco to provide a WAN with broadcast capabilities. I connect

my routers via serial over this WAN and

i use cisco HDLC.


Would it be possible for the routers to

communicate?


thanks,

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

a broadcast capable WAN infrastructure.

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

Giuseppe
