I can say toward the starting that more colleagues is going by this online journal. At last systems administration information task did succeed to get a few fans from out there so I felt the need to thank all of you for going to this spot. As should be obvious here from the blog entry list I didn't take after this development myself nowadays. I really didn't come here for quite a while. My most recent couple of weeks where extremely exceptional. A reason was my learning sessions that took me no less than few hour a day and the most intriguing reason was my new task at work. I got a task to do and much all the more intriguing to secure IPv6 in our organization for an entire system section. No less than one portion for the present, yet it was a pleasant thing to get me into IPv6 profound plunge learning. Furthermore, I make the last stride of the learning like this:
What is superior to anything report the systems administration work that you did until is new in your mind. So I record it for the future usage yet rather than place it into my scratch pad I do it here on my site, so next time is less demanding to scan for it and something far and away superior to that, you can utilize it to.
This time I will expound on probably the most critical thing in IPv6 organizing that you expected to know before you go on and do IPv6 execution. RA switch promotions and some abnormal extraordinary bits in the RA parcel header that are design alternative banners. It's fortunate is that there are just few of them, four to be exact. The awful thing is that at first I required couple of days to quit blending them up.
There are initial two banners:
1 These two are dependably in the RA notice bundle and they are telling the host how he can get his IPv6 address. M banner – remains for Managed Address Configuration and it says to host accepting the RA ad that some place in his system there is a DHCPv6 server accessible and that he ought to send a DHCPv6 solicitation out of his interface to get his IPv6 address. Obviously, if the M banner is changed to 0 we say that the banner is cleared and that implies fundamentally that host won't attempt to get his location from DHCPv6 server and that it will most likely attempt to autoconfigure himself with SLAAC.
2 The following banner is O banner. O banner stands for Other design and it tells host getting the RA message that he ought to utilize DHCP to get other arrangement parts like DNS server IPv6 address and something else perhaps. This is very was for the time being to get DNS information on the host, SLAAC in todays execution it's not ready to send the data to have about DNS server IPv6 address. That will most likely constrain you to utilize both SLAAC and DHCPv6 to on those subsets where you need to utilize programmed host setup strategy.
There is RFC 6101 that indicates in what capacity will IPv6 Router Advertisement permit IPv6 switches to give a DNS server location rundown to utilizing RA switch commercial message. For the time being I didn't know about this being executed in Cisco IOS or some other switch OS. One day it will be and you will have the capacity to truly picked in the middle of SLAAC and DHCPv6.
There are two more banners:
3 You will most likely put prefix data in RA messages to say to have what prefix of the IPv6 location to utilize when they autoconfigure themselves. On the off chance that you utilize banner L you will say to the host that gets that RA that different gadgets with the same prefix are on the same subnet. To make it less complex, you will instruct them to talk between them utilizing just switch (L2) and not to send each message to the switch and after that from switch to other host on the same subnet.
4 The last banner is A banner. This one is programmed one and the name A likely stands for Address Configuration Flag. This one will advise the host to utilize the prefix inside RA and his own particular NIC macintosh address and produce his own particular IPv6 address. Just said use SLAAC (Stateless location autoconfiguration). This strategy utilizes EUI-64 technique for creating the IPv6 address so you can read more about SLAAC and EUI-64 on the post connected her
