BSCI communicating success is every conception of decent a CCNP, and conception of that success is today acquisition the principle of IP Version 6, or IPv6. One of the most arduous parts of acquisition IPv6 concepts is the radically assorted addressing plot that IPv6 uses as compared to IPv4. Just countenance at these distribution addresses:

Typical IPv4 address: 129.14.12.200

Typical IPv6 address: 1029:9183:81AE:0000:0000:0AC1:2143:019B

As you crapper see, IPv6 isn’t meet meet tacking digit more octets onto an IPv4 address!

I haven’t met likewise whatever networkers who rattling same typing, specially numbers. You’ll be bright to undergo there are whatever rules that module shorten those addresses a bit, and it’s a rattling beatific intent to be smooth with these rules for your exam.

You advert from your CCNA studies that there’s no disagreement between an upper-case honor and lower-case honor in hexadecimal. That’s digit of threesome base rules you requirement to undergo when employed with IPv6 addressing. The added factors care with every the zeroes you’ll separate into in IPv6 addresses! One of these rules is the conception of set compression.

The conception of set densification states that if an come contains serial fields of zeroes, they crapper be spoken with digit colons. It doesn’t concern if you hit digit fields or eight, you crapper exclusive identify digit colons and that module equal every of them. The key here is that you crapper exclusive do this erst in an IPv6 address. This is referred to as set compression. Here’s an example:

Original format: 1234:1234:0000:0000:0000:0000:3456:3434

Using set compression: 1234:1234::3456:3434

Again, you staleness advert that you crapper exclusive do this erst in an IPv6 come expression.

What if there are zeroes in the come that don’t quite sound this rule? The incoming conception of our IPv6 tutorial module care with directive set compression, added agency you crapper ingest to shorten these long, daylong addresses!

This is also where you crapper apace move drowning in acronyms! The cost “RAM” and “ROM” belike aren’t newborn to you, but ownership up with “what goes where” with RAM, ROM, NVRAM, and Flash Memory crapper be quite a challenge! In this tutorial, we’ll verify a countenance at every quaternary of these components and their contents.

ROM stands for Read-Only Memory. storage stores the router’s bootstrap start program, operative grouping software, and power-on characteristic effort programs (the POST).

Flash module is mostly referred to as “flash” The Cisco Internetwork Operating System (IOS) images are held here. Flash is eradicable and reprogrammable ROM. Flash module noesis is preserved by the router on power-down or reload.

RAM is brief for Random-Access Memory. RAM on a Cisco router stores effective aggregation much as routing tables and the streaming plan file. RAM table are forfeited when the router is supercharged downbound or reloaded.

NVRAM is non-volatile RAM. By “non-volatile”, we stingy that the table of NVRAM are not forfeited when the router is supercharged downbound or reloaded. Where RAM holds the streaming plan file, NVRAM holds the start plan file. If NVRAM is blank when the router reloads, you module be prompted to start falsehood mode.

Success on the CCNA communicating depends on ownership these cost straightforward and lettered their contents. Know the table of each, clear primary tending to what is forfeited on a charge and what is not, and you’re on your artefact to CCNA communicating success!
