Cisco CCNP Accreditation

De BISAWiki

Moving the BSCI exam and earning your CCNP certification demands that you add significantly towards the networking skills foundation you made when you learned on your CCNA certification. We discovered www.lawholesaleroute.com/ by searching books in the library. You learned quite a bit about static routing and default static routing when you handed the CCNA test, and it will appear to be that needs to be all you need to find out about static routing, right?

One thing you'll learn when you continue to generate Cisco certifications is that there's always something else to learn! You may have heard the term 'floating static route', which does propose some interesting mental pictures. 'Floating'? Sailing on what?

You might say, a static route is 'floating' in your routing table. A floating static route is a route which is used only when tracks for the same location but using a lower administrative distance are taken from the table. For instance, you may be having an OSPF-discovered route as your primary route to certain destination, and the floating static route would serve as a route that would be used only if the OSPF route leaves the routing table.

Now, how can that happen? After-all, OSPF has an administrative length of 110 and static routes have ADs of just one or zero, depending on whether it is constructed with a next-hop IP-ADDRESS or a nearby exit interface. One of the ways or the other, 0 and 1 remain less than 110!

You should assign the route an AD greater than that of the main route, when you want to change a static route. In this case, we've surely got to develop a fixed route using an AD higher-than 110. We do that by using the 'distance' option at the conclusion of the 'ip route' command.

R1( config )#ip path 110.1.1.0 255.255.255.0 172.12.123.1??

R1( config )#ip path 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 will be the AD of that route. If there is an route for 110.1.1.0 /24, that will be the primary route, and the floating static route will not be utilized until the OSPF route is removed from the routing table.

Floating static routes aren't merely a good thing to know for the BSCI assessment and your CCNP accreditation desire - they are very realistic in the real-world too.
