1 00:00:06,970 --> 00:00:15,070 For two sides to exchange replication data a site link must connect them a site link is a logical path 2 00:00:15,370 --> 00:00:23,950 that the knowledge consistency checker and I S T G use to establish replication between sites. 3 00:00:24,010 --> 00:00:32,230 When you create additional sites you must select at least one site link that will connect the new site 4 00:00:32,470 --> 00:00:36,690 to an existing site unless a site link is in place. 5 00:00:36,790 --> 00:00:44,680 The knowledge consistency checker cannot make connections between computers at different sites nor can 6 00:00:44,680 --> 00:00:47,670 replication or cure between sites. 7 00:00:47,680 --> 00:00:54,960 It is important to remember that a site link represents an away label path for replication. 8 00:00:55,120 --> 00:01:00,520 A single site link does not control the network crowds that are used. 9 00:01:00,520 --> 00:01:08,770 When you create a site link and add sites to it you tell it it is that it can replicate between any 10 00:01:08,770 --> 00:01:18,820 of the sites that are associated with a sidling the IRS to g create connection objects and those objects 11 00:01:18,820 --> 00:01:22,140 will determine the actual replication path. 12 00:01:22,210 --> 00:01:30,460 Although their application topology that the IRS T.J. builds does replicate the ideas effectively. 13 00:01:30,610 --> 00:01:37,960 It might not be efficient with your network topology to understand this concept better. 14 00:01:37,960 --> 00:01:47,350 Consider the following example when you create a forest one site link object is created which is default 15 00:01:47,680 --> 00:01:50,260 IP site link by default. 16 00:01:50,290 --> 00:01:56,590 Each new site that you add is associated with default IP site link. 17 00:01:56,620 --> 00:02:04,900 This site link and any other existing site links have a default cost of 100 and a default replication 18 00:02:04,900 --> 00:02:07,810 period of 1 8 minutes. 19 00:02:07,810 --> 00:02:15,560 Consider the example of an organization with three branch offices and a data center or the head quarters. 20 00:02:15,640 --> 00:02:21,700 The three branch offices each connect to the data center with a dedicated link. 21 00:02:21,790 --> 00:02:31,470 You create sites for each branch office namely Seattle LCA Amsterdam air mass and Beijing. 22 00:02:31,510 --> 00:02:40,660 Each of the sites including headquarters is associated with the default IP site link site link object 23 00:02:40,990 --> 00:02:50,020 because all four sites are on the same side link your instructing aided Is that all four sides can replicate 24 00:02:50,260 --> 00:02:51,390 with each other. 25 00:02:51,520 --> 00:02:59,740 And that means that Seattle might replicate changes from Amsterdam Amsterdam might replicate changes 26 00:02:59,740 --> 00:03:07,840 from Beijing and Beijing might replicate changes from the headquarters region dorm replicate changes 27 00:03:07,840 --> 00:03:15,040 from Seattle in several of these replication paths replication traffic on the network flows through 28 00:03:15,040 --> 00:03:20,920 the headquarters on its way from one branch to another with a single site link. 29 00:03:20,920 --> 00:03:29,080 You do not create a hub and spoke replication topology even though your network topology is hub and 30 00:03:29,080 --> 00:03:37,240 spoke to align your network topology is a tedious replication you must create specific side links that 31 00:03:37,240 --> 00:03:45,460 is you can manually create side links and reflect your intended replication topology continuum. 32 00:03:45,480 --> 00:03:53,710 The precedent example you would create three site links as follows headquarter of Amsterdam includes 33 00:03:53,710 --> 00:04:03,340 their headquarters and Amsterdam sites HQ Sia includes their headquarters and Seattle sites and HQ by 34 00:04:03,340 --> 00:04:06,860 June includes the headquarters and Beijing sites. 35 00:04:06,880 --> 00:04:15,010 After you create site links there I asked a Jew uses the topology to build an entire site replication 36 00:04:15,010 --> 00:04:23,290 topology that connects each site and then create connection objects automatically to configure their 37 00:04:23,290 --> 00:04:26,080 application path as a best practice. 38 00:04:26,080 --> 00:04:33,450 You should configure your site topology correctly and avoid create and connection objects manually.
