I was watchin some rip class today and in the excersice it was a router connected to other 3 routers. ok so he wanted this the R1 knows 3 paths to the same destination 1 via rip and 2 via static but he told us ok if the Rip route fails any static route must replace it .ok

but static Admistrative distance is 1 so i thought the router should pick the static over the Rip route no viceversa so should i configure AD of rip to 0 to surpass Static right.

    No.

    You can create a Floating Static Route to "backup" the dynamic protocols.
    You'd actually set the Administrative Distance on the backup Floating Static Route to a value higher than the value of the Administrative Distance of the Dynamic Routing Protocol.

    AD rules all. If dealing with default values, static wins. Sure he wasn't talking about hop count versus link speeds?

    Longest match rules all, so it could have been a less specific static that would be used if the RIP route was lost.

    Just theorizing here.

    Well, duh. At this level, unless explicitly called out in a given example I think we can assume that the match lengths are identical when it comes to explaining how AD works in choice of routes.
