Subject: Challenge : HSRP

> Hi guys,
>
> I've got a challenging question i worked on last week regarding HSRP.
> The solution is not so trivial, and it took me a while to find the answer
> (so i hope you won't find the solution too quickly ;o)
>
> Just let's go :
>
> R1,R2, and R3 routers are full-meshed over FR,
> using point-to-multipoint interfaces.
>
> R1 and R2 are also connected via Ethernet.
> R3 has an LAN interface (Eth, or Token. As you wish)
>
> You are running HSRP between R1 and R2 ; and R1 is your Active router by
> default.
>
> What you want to do is to configure the routers so that
> R2 becomes the Active router IF and ONLY IF the DLCI between R1 and R3
fall
> down.
>
> Note: You have to run OSPF on the FR cloud (R1, R2, R3 are in Area 0)
>
> Good luck,
> and please don't ridiculate me finding the solution in 3 minutes ;o)

> Cheers.
