I can say toward the starting that more colleagues is going to this website. At long last systems administration learning venture did succeed to get a few fans from out there so I felt the need to thank all of you for going by 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 exceptionally extreme. A reason was my learning sessions that took me no less than few hour a day and the most fascinating reason was my new task at work. I got a task to complete and significantly all the more fascinating to secure IPv6 in our organization for an entire system fragment. No less than one fragment until further notice, however it was a decent thing to get me into IPv6 profound jump learning. Also, I make the last stride of the learning like this:
What is superior to anything record the systems administration work that you did until is crisp in your mind. So I record it for the future usage but instead than place it into my scratch pad I do it here on my online journal, so next time is less demanding to hunt down it and something shockingly better than that, you can utilize it to.
This time I will expound on the absolute most imperative thing in IPv6 organizing that you expected to know before you go on and do IPv6 usage. RA switch ads and some bizarre uncommon bits in the RA parcel header that are setup choice banners. It's fortunate is that there are just few of them, four to be exact. The terrible 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 parcel 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 getting the RA promotion 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 essentially 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 arrangement and it tells host accepting the RA message that he ought to utilize DHCP to get other setup parts like DNS server IPv6 address and something else perhaps. This is quite was until further notice 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 drive you to utilize both SLAAC and DHCPv6 to on those subsets where you need to utilize programmed host arrangement technique.
There is RFC 6101 that determines by what means will IPv6 Router Advertisement permit IPv6 switches to give a DNS server location rundown to utilizing RA switch promotion message. Until further notice I didn't know about this being actualized 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 presumably put prefix data in RA messages to say to have what prefix of the IPv6 location to utilize when they autoconfigure themselves. In the event 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 difficult, 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 most 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 create his own IPv6 address. Essentially said use SLAAC (Stateless location autoconfiguration). This strategy utilizes EUI-64 technique for producing the IPv6 address so you can read more about SLAAC and EUI-64 on the post conne
