Routing Protocols

Image
What is a routing protocol? A  routing protocol  specifies how  routers  communicate with each other to distribute information that enables them to select routes between  nodes  on a  computer network . Data packets  are, forwarded through the networks of the internet from router to router until they reach their destination computer.  Routing  algorithms determine the specific choice of route r . Each router has a prior knowledge only of networks attached to it directly. A routing protocol shares this information first among immediate neighbors, and then throughout the network. This way, routers gain knowledge of the   topology of the network .

JEA(Just Enough Administration)

   We will done this configuration by PowerShell, Step 1 Open PowerShell in Domain controller and execute New-PSSessionConfigurationFile -Path 'C:\Program Files\WindowsPowerShell\spooler_conf.pssc' notepad 'C:\Program Files\WindowsPowerShell\spooler_conf.pssc' After executed that command also execute this command to open notepad filev   Now Change the notepad file that have open. You should not change the all, Just change I mention here      Step-2 To Creating a folder for JEA execute this command New-Item –Path 'C:\Program Files\WindowsPowerShell\Modules\JEA\RoleCapabilities' -ItemType Directory     Step-3 (Creating the PS Role Capability File for the Spooler Admins (psrc file): Put this command in PowerShell New-PSRoleCapabilityFile -Path 'C:\Program Files\WindowsPowerShell\Modules\JEA\RoleCapabilities\spooler_admins.psrc' After executed that command also execute this command to open notepad file notepad 'C:\Program Files\Win...

IP ADDRESS

IP Address: 1.   A Unique Identifier 2.   A way to identify machine / computer on a network 3.   Use to connect to another computer IP Address can be IPv4 and IPv6 IPv4 IP Address IP Address Classification   MAC Address vs IP Address CIDR

VLAN Configuration

Image
  VLANs are used to divide a physical LAN into multiple broadcast domains to isolate services with the aim of improving the security and management of the network. Hosts within a VLAN can directly communicate only with other hosts in the same VLAN and must use a router to communicate with hosts in other VLANs. Put IP Address to every PC Like this:   PC0   PC1     Now go to Switch CLI mode and done those command:     Here are the Configuration command for two Switch:     Switch> Switch>en Switch# Switch#conf t Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#vlan 15 Switch(config-vlan)#name SRK Switch(config-vlan)# Switch(config-vlan)#ex Switch(config)# Switch(config)#vlan 16 Switch(config-vlan)#name SK Switch(config-vlan)#ex Switch(config)# Switch(config)#int range f0/1-2 Switch(config-if-range)#switchport mode access Switch(config-if-range)...

MAC Blinding in DHCP-Server on GNS3

Image
    If we want to make a FTP-server in network 172 and network 192. We have to give same IP address in FTP-Server. So we have to make sure that every time that FTP-Server get same IP address so that user can access. In R1 we gone create DHCP-server for two different network. Let’s starts R1 Configuration R1#conf R1(config)#hostname DHCP-Server DHCP-Server(config)#int f0/0 DHCP-Server(config-if)#no sh DHCP-Server(config-if)#ip add 172.16.32.1 255.255.254.0 DHCP-Server(config-if)#ex DHCP-Server(config)#int f0/1 DHCP-Server(config-if)#no sh DHCP-Server(config-if)# DHCP-Server(config-if)#ip add 192.168.10.1 255.255.255.0 DHCP-Server(config-if)#ex Create two different POOL for 192.168.10.0 and 172.16.32.0 network For network 192.168.10.0 For network 172.16.32.0 Now we are done with our configuration …now just put command ip dhcp in all pc for automatic IP address.   PC 1 PC2 PC3 PC4 PC5 PC6 Now we can see in PC5 & PC6 IP address is assign. But we will blind IP address 172....
