Cisco CCNP / BSCI Assessment Tutorial: Leading Zero Pressure

The BSCI assessment and CCNP certification requires that you be well versed in the fundamentals of Internet Protocol Address Version 6, or IPv6. If you're a new comer to IPv6, you'll quickly learn that it is nearly just two more octets slapped onto an IPv4 address! IPv6 addresses are quite long, but there are two strategies to acceptably shorten IPv6 target expression. To complete the BSCI test, become a CCNP, and get that all-important understanding of IPv6, you have got to comprehend these different methods of showing an IPv6 address. My last IPv6 training discussed zero compression; to-day we'll take a peek at primary zero compression.
Leading zero retention allows us to shed the leading zeroes from every area in the handle. Where we could only use zero compression once in an IPv6 address expression, leading zero compression can be used as frequently as is appropriate. The key with leading zero compression is that there must be at least one number left in each field, even if that remaining number is a zero.
You sometimes see books or websites refer to primary zero pressure as 'losing zeroes and replacing them with a', but that description could be a little confusing, since the blocks are divided with a colon to start with. You're not necessarily changing the best zeroes, you are dropping them.
Let us take a look at a typical example of leading zero pressure. Using the address 1234:0000:1234:0000:1234:0000:1234:0123, we have four different areas that have leading zeroes. The target could possibly be written out as it is, or drop the leading zeroes.
Original format: 1234:0000:1234:0000:1234:0000:0123:1234
With leading zero compression: 1234:0:1234:0:1234:0:123:1234
There's no problem with applying zero compression and top zero compression in the sam-e address, as shown here:
Unique format: 1111:0000:0000:1234:0011:0022:0033:0044
With zero and leading zero compression: 1111::1234:11:22:33:44
Zero compression uses the double-colon to-replace the 2nd and third block of figures, which were all zeroes; leading zero compression replaced the '00' at the beginning of each of the past four blocks.

You should be careful and invest some time with both zero compression and leading zero compression and you'll do well on the exam and in the real-world. The keys to success listed below are remembering that you can only use zero compression once-in a single target, and that while primary zero compression can be used as frequently as needed, at least one number must stay in each field, even when that number is a zero..
