just joined the site. and the labs exercises are awesome. love 'em, thanks. right now, I'm preparing for my CCNP ROUTE new exam. I'm trying to do this lab and I was able to configure Paris, Berlin, and Stockholm. but was unable to achieve full IP connectivity. maybe I didn't read properly, but do we need to also configure the frame relay switch - I previously thought it was pre-configured. thank you.
Frame-Relay Basics
Scenario
As a CCNA candidate you are familiar with the concept of Frame-Relay, although you do not need to configure the Frame-Relay switch. Since you are working your way to becoming the ultimate networking Guru, you are prepared to do a full Frame-Relay config....that includes the Frame-Relay Switch! Configuring a point-to-multipoint and point-to-point PVC and having ip connectivity is your goal.
Goal:
- Take a good look at the topology before you start configuring.
- The green lines are PVC's (Permanent Virtual Circuit) and this is supposed to be a point-to-multipoint.
- Paris should be the "hub" and Berlin and Stockholm are "spoke" routers.
- The blue line is a point-to-point PVC between Paris and Berlin.
- DLCI numbers are shown on the topology picture.
- Use the 192.168.123.0 /24 subnet for the point-to-multipoint connection, use a subinterface.
- Use the 192.168.12.0 /24 subnet for the point-to-point connection, use a subinterface.
- Achieve full IP connectivity, all ip addresses should be pingable.

galen_kwan 2010-11-27 10:22:10never mind, I managed to get full IP connectivity, by replacing the centre router with the frame relay switch, thanks.

I did configure all my device in this lab. I speak about frame-relay multipoint network (192.168.123.0/24). And achieved IP connectivity btw all routers, but all routers can't ping ip address of own frame-relay multipoint interfece.
This is normal?

ReneMolenaar 2011-04-04 21:38:30Not being able to ping your own IP address with frame relay is normal, if you want to be able to do so you must create a frame relay "map" for your own IP address.

luismg 2011-04-05 10:04:55I don't know why don't you put a frame relay switch in the middle.
Not on even CCIE R&S you need to configure a router as a frame relay switchkind regards

I'd rather take the "Cisco" solution for the frame relay switch than the "gns3" solution. It works perfect but this way people can learn how to configure one if they have a real cisco router as well.
Unless you have an older computer running an extra router shouldn't be a problem.

I first solved it, then compared my souliton with your final Configs and found something missing.Berlin#pi 192.168.123.1
