Cisco CCNP Certification / BSCI Exam Tutorial: Floating Static Routes

BSCI passes the examination and obtain certification CCNP demands that you add greatly to the capabilities of networks has created a foundation that when you studied for certification CCNA. You learned a lot about routing and static routing default when it approved the CCNA test, and it does seem like it should be all you need to know about static routing, right?
One thing you learn as you continue to earn Cisco certifications is that there is always something more to learn! You may have heard the term " route static floating ", which suggests some interesting mental images. Floating " "? Floating on what?
In somehow a route is static floating " " floating in its routing table. A floating static route is a route that will be used only if the routes for the same destination, but with a smaller distance administrative withdrew from the table. For example, you could be using a OSPF-discovered the route as its main route to a specified destination, and the route would serve as floating static route a backup to be used only if the OSPF route leaves the route table.
Now, How can that happen? After all, OSPF has an administrative distance of 110 routes and static ads have one or zero, depending on whether it is configured with a next-hop IP address or a local output interface. One way or another, 1 and 0 are still less than 110!
When you want to set up a route static floating, you must allocate the route of a DP higher than that of the main route. In this case, we have come to create a static route with a greater than 110 AD. We do so through the use of distance " " at the end of the " ip route " command.
R1 (config) ip route 110.1.1.0 255.255.255.0 172.12.123.1?
Distance metrics for this route
name Enter the name of the next hop
permanent permanent route
tag September label for this route

R1 (config) ip route 110.1.1.0 255.255.255.0 172.12.123.1 111
The number came at the end of the " ip route " DP is of that route. If there is a route for OSPF 110.1.1.0 / 24, which will be the main route and the route static floating not be used unless the route is removed from the OSPF route table.
Floating routes are not only a good you need to know for the review of its certification CCNP BSCI and exercise - are very practical in the real world as well.
