Site “XXX” Challenges and ImplementationSite details and ChallengesReduce Broadcast domain using Vlan and Implementation of redundancy in LAN.Currently network design is in one broadcast domain, so there is speed slow issues and highlatency in network.Current network design has no redundancy due to this, if one device or one link goes down thenall end user not able to access network.Site Solution and Technologies1)To reduce broadcast domain, need to implement vlan in LAN. Currently there is one vlanwhich means one broadcast domain. So I am going to create 3 vlan for this scenario, onebroadcast domain is going to break in 3 broadcast domain, so network perform will beefficient. Vlan details as mention below.2)Currently, there is no redundancy in network in terms of devices and links. There is oneLayer-3 switch as backbone of network and there is one link use for connectivity betweenLayer-3 switch and Layer-2 switches. I am going to implement redundant Layer-3 switch andring network architecture. Need to configure Spanning tree for redundancy of Links andHSRP for redundancy of Devices.Spanning tree protocol design for loop prevention in network, now it used beyond loopprevention as redundancy. STP detect look using BPDU packet. Switch send BPDU packetout of all interface and when the switch get the packet back, switch consider loop in networkand block that port where BPDU received.Sample ConfigurationBasic configurationswitch(config)#hostname XXXXXX(config)#banner motd ^AUTHORIZED ACCESS ONLYIf you are not authorized to access then disconnect immediately.^XXX(config)#banner login ^AUTHORIZED ACCESS ONLY^
