When you happen to be working on your BCMSN exam on your way to CCNP certification, you'll read at length about how Cisco routers and multilayer switches can work to provide router redundancy - but there's yet another beneficial service, Server Load Balancing, that does the very same for servers. When HSRP, VRRP, and CLBP all represent a number of physical routers to hosts as a single virtual router, SLB represents several physical servers to hosts as a single virtual server. In the following example, three physical servers have been placed into the SRB group ServFarm. They're represented to the hosts as the virtual server 210.1.1.14. The hosts will seek to communicate with the server at 210.1.1.14, not knowing that they're really communicating with the routers in ServFarm. This allows rapid cutover if one of the physical servers goes down, and also serves to hide the actual IP addresses of the servers in ServFarm. The simple operations of SLB includes creating the server farm, followed by making the virtual server. To get further information, you should check out http://www.kswo.com/story/30394774/mathfilefoldergamescom-hosts-virtual-math-summit. We'll 1st add 210.1.1.11 to the server farm MLS(config)# ip slb serverfarm ServFarm MLS(config-slb-sfarm)# true 210.1.1.11 MLS(config-slb-real)# inservice The 1st command creates the server farm, with the actual command specifying the IP address of the true server. The inservice command is needed by SLB to look into the server as ready to manage the server farm's workload. The real and inservice commands need to be repeated for each and every server in the server farm. To build the virtual server MLS(config)# ip slb vserver VIRTUAL_SERVER MLS(config-slb-vserver)# serverfarm ServFarm MLS(config-slb-vserver)# virtual 210.1.1.14 MLS(config-slb-vserver)# inservice From the leading down, the vserver was named VIRTUAL_SERVER, which represents the server farm ServFarm. The virtual server is assigned the IP address 210.1.1.14, and connections are allowed when the inservice command is applied. You may perhaps also want to handle which of your network hosts can connect to the virtual server. If hosts or subnets are named with the client command, these will be the only consumers that can connect to the virtual server. To get different viewpoints, we recommend you have a glance at MathFileFolderGames.com Hosts Virtual Math Summit. Note that this command utilizes wildcard masks. The following configuration would let only the hosts on the subnet 210.1.1. If you think anything at all, you will maybe choose to explore about MathFileFolderGames.com Hosts Virtual Math Summit. /24 to connect to the virtual server. MLS(config-slb-vserver)# client 210.1.1.
