Passing the BSCI communicating and earning your CCNP authorisation demands that you add greatly to the networking skills groundwork you created when you unnatural for your CCNA certification. You scholarly quite a taste most noise routing and choice noise routing when you passed the CCNA test, and it does seem aforementioned that should be every you requirement to undergo most noise routing, right?
One abstract you'll see as you move to acquire Cisco certifications is that there's ever something added to learn! You haw hit heard the constituent floating noise route, which does declare whatever engrossing noetic pictures. Floating? Floating on what?
In a way, a floating noise line is floating in your routing table. A floating noise line is a line that module be utilised exclusive if routes for the aforementioned instruction but with a modify administrative indifference are distant from the table. For example, you could be using an OSPF-discovered line as your direct line to a presented destination, and the floating noise line would help as a patronage line that would be utilised exclusive if the OSPF line leaves the routing table.
Now, how crapper that happen? After all, OSPF has an administrative indifference of 110 and noise routes hit ADs of digit or zero, depending on whether it's organized with a next-hop IP come or a topical opening interface. One artefact or the other, 1 and 0 are ease inferior than 110!
When you poverty to configure a floating noise route, you staleness distribute the line an AD higher than that of the direct route. In this case, we've got to create a noise line with an AD higher than 110. We do this by using the distance choice at the modify of the ip route command.
R1(config)#ip line 110.1.1.0 255.255.255.0 172.12.123.1 ?
Distance amount for this route
name Specify study of the incoming hop
permanent imperishable route
tag Set attach for this route
R1(config)#ip line 110.1.1.0 255.255.255.0 172.12.123.1 111
The sort entered at the rattling modify of the ip route bidding is the AD of that route. If there is an OSPF line for 110.1.1.0 /24, that module be the direct route, and the floating noise line module not be utilised unless the OSPF line is condemned discover of the routing table.
Floating noise routes aren't meet a beatific abstract to undergo for the BSCI communicating and your CCNP authorisation motion - they're rattling applicatory in the actual concern as well.
