Cisco CCNP Certification BSCI Test Tutorial: Floating Static Routes




Driving the BSCI test and getting your CCNP certification demands that you add significantly to the networking skills base you created when you learned to your CCNA certification. You learned quite a bit about default static and static routing routing when you passed the CCNA test, and it does seem like that needs to be all you have to know about static routing, right? 

A very important factor you'll learn as you keep on to earn Cisco certifications is that there is always something else to learn! You may have heard the word 'floating static route', which does propose some interesting mental pictures. 'Floating'? Flying about what? 

In a way, a static route is 'floating' in-your routing table. A floating static route is a route which will be used only when paths for the same destination-but using a lower administrative distance are taken off the table. Like, you will be using an OSPF-discovered route as much of your route to certain destination, and the floating static route would serve as a route that would be utilized only if the OSPF route leaves the routing table.

Now, how can that happen? In the end, OSPF has an administrative length of 110 and static routes have ADs of 1 or zero, according to whether it is configured with a next-hop IP address or a nearby exit program. One-way or another, 1 and 0 remain less than 110! 

When you need to manage a static route, you should determine the route an AD higher-than that of the primary route.

[http://www.parkercountyvet.com/ Texas Vets] includes further concerning the purpose of this thing. We do that by using the 'distance' option at the end of-the 'internet protocol address route' command. 

R1( config )ip way 110.1.1.0 255.255.255.0 172.12.123.1?? 

1-255 Distance full for this way 

name Specify name of the next jump 

permanent permanent option 

tag Set tag with this path 

R1( config )ip option 110.1.1.0 255.255.255.0 172.12.123.1 1-11 

The quantity entered at the very end of the 'ip address route' command could be the AD of that route. If you have an route for 110.1.1.0 /24, that will be the main route, and the floating static route will not be utilized until the OSPF route is taken out of the routing table. 

Floating static routes are not merely a positive thing to understand for your CCNP accreditation quest and the BSCI assessment - they are very practical in-the real life also.
