Floating Static Routes

SV

Hi,

I went for an interview yesterday and one of the question was about Floating Static Routes. Though I was not able to answer at that point, I did search about it on the net.

Thought it will be good to post about the same.

"Floating static routes are static routes that have an administrative distance greater than the administrative distance of dynamic routes. Administrative distances can be configured on a static route so that the static route is less desirable than a dynamic route. In this manner, the static route is not used when the dynamic route is available. However, if the dynamic route is lost, the static route can take over, and the traffic can be sent through this alternate route. If this alternate route uses a Dial-on-Demand Routing (DDR) interface, then that interface can be used as a backup feature."
