It is a technique where you distrubute your static ip addresses in EIGRP.

If you create a static IP route, it will not be distributed by EIGRP standard, with redistribute static it will.

If there are multiple routes with the same Administrative distance it will choose the one with the most specific Subnet mask. so a /32 is prefered over a /24.

If subnet mask are the same it will go for the lowest score based on the DUAL calculation if I'm not wrong.

btw, why change your EIGRP towards Distance 1 ?

As far as I know, the order in which routes are selected is as follows:

1. The most specific route is selected among all routes that cover the destination address of the packet.

If more than one route match then:

2. The route with the lowest Administrative Distance is chosen.

If more than one route has the same AD:

3. The route with the lowest metric is chosen.

If more than one route has the same metric:

4. The router chooses any route arbitrarily or load balance between them.

So, As Chojin said it will choose the most specific route. And thats a priority before the Administrative Distance. So even if the EIGRP route had it's normal AD (90, or any thing) and the static route had AD 1. It will still choose the EIGRP route if it's the most specific. As it will also choose the static one if it's the most specific.

Experts please correct if wrong.

Just a small correction here in 4.

4. The router chooses any route arbitrarily or load balance between them.

It depends on the routing protocol. Most of them RIP, EIGRP, etc.. will load balance.
