Week-end equals some fun. First of all, I think I can give you some fun for around 30mn.

For my side, it was this. It will be cool to tshoot this little MPLS topology :

Thanks to Daniel for this MPLS troubleshoot session :)

During this tech fun session, I invit you to listen to : http://youtu.be/3f-JhB9ZfZQ

CCIP diploma has finally arrived at home :)

Here it is a little challenge. You will find two CPE connected to two different PE. The two CPE are used in "fail-over" model by using HSRP. The two CPE dial on PE. CPEprimaire dials through a Bridge, CPESecondaire dials directly.

CPEPrimaire :
-------------
on LAN fastethernet:
standby 5 ip 10.0.0.1 
standby 5 preempt
standby 5 track Dialer 1
standby 5 priority 105

CPESecondaire :
---------------
on LAN fastethernet :
standby 5 ip 10.0.0.1
standby 5 preempt

Do you think when link between PE75 and Bridge will be DOWN, HSRP will act as waited : PCs on LAN will have for gateway CPESecondaire ? You can shut interface WAN on bridge to try it. I enclosed GNS3 lab : hsrp-challenge.

Just to give you a new challenge. It is supplied by IPexpert.
