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.
