The Frame Relay switch is configured DLCI-DLCI in your config file, but you dont actually have telnet access to it.

If you look at the state of the Frame switch you will see it is n/a instead of stopped or started.

Hi Solpandor

Just to add my 2 cents worth if I may.

The generic frame switch in dynamips provides a full mesh frame relay topology and as has already been pointed out you can not access this frame switch.

However you could configure a normal router in dynamips as a frame switch the same way you would in a home lab and configure point to point or point to multipoint links and in this instance you would have access to the frame switch.

Here are two links I came across when I was running frame relay on dynamips myself


Best Regards,
