Start Configuring OSP on each Router One by One:

In this lab you have to use wild card mask in place of subnet mask while doing routing.

Note: Here I am not going to show you how to configure ip address.I assume you guys already have an idea how to assign ip address.


OSPF Routing Configuration on Router0:


Router(config)#route ospf 1

Router(config-router)#network 20.0.0.0 0.255.255.255 area 0

Router(config-router)#network 10.0.0.0 0.255.255.255 area 0

Router(config-router)#net 30.0.0.0 0.255.255.255 area 0


OSPF Routing Configuration on Router1:


Router(config)#route ospf 1

Router(config-router)#net 40.0.0.0 0.255.255.255 area 0

Router(config-router)#net 50.0.0.0 0.255.255.255 area 0

Router(config-router)#net 60.0.0.0 0.255.255.255 area 0


OSPF Routing Configuration on Router2:


Router(config)#route ospf 1

Router(config-router)#net 70.0.0.0 0.255.255.255 area 0

Router(config-router)#net 80.0.0.0 0.255.255.255 area 0

Router(config-router)#net 90.0.0.0 0.255.255.255 area 0


OSPF Routing Configuration on Router3:


Router(config)#route ospf 1

Router(config-router)#net 100.0.0.0 0.255.255.255 area 0

Router(config-router)#net 101.0.0.0 0.255.255.255 area 0

Router(config-router)#net 102.0.0.0 0.255.255.255 area 0



OSPF Routing Configuration on Router4:


Router(config)#route ospf 1

Router(config-router)#net 103.0.0.0 0.255.255.255 area 0

Router(config-router)#net 104.0.0.0 0.255.255.255 area 0

How to Assign IP Address Linux in RHEL 5 & RHEL 6

In this Tutorial I am going to show how to assign Permanent IP Address in Linux. Specially RedHat and CentOS 5 Linux.

 First you have to do is to Log on as root user and go to the Directory  /etc/sysconfig/network-scripts/ to view all available devices.

    # cd /etc/sysconfig/network-scripts/

You need to edit following files:

    /etc/sysconfig/network-scripts/ifcfg-eth0 ( First Ethernet card configuration file)
    /etc/sysconfig/network-scripts/ifcfg-eth1  ( Second Ethernet card configuration file)

To edit/create first NIC file, type command:

    # vim ifcfg-eth0

Append/modify as follows:

    DEVICE=eth0
    BOOTPROTO=static
    DHCPCLASS=
    HWADDR=00:30:48:56:A6:2E
    IPADDR=192.168.1.100
    NETMASK=255.255.255.0
    ONBOOT=yes

Save and close the file. (:wq!)

After that, configure the default gateway (router IP) and hostname in /etc/sysconfig/network file:

    # vim /etc/sysconfig/network

Append/modify configuration as follows:

    NETWORKING=yes
    HOSTNAME=opesource
    GATEWAY=192.168.1.1

Save and close the file(:wq!). Restart networking by enter following command:

    # /etc/init.d/network restart

Make sure you have correct DNS server defined in /etc/resolv.conf file:

    # vi /etc/resolv.conf

Setup DNS Server as follows:

    nameserver  8.8.8.8
    nameserver  8.8.4.4

Save and close the file(:wq!). Now you can check(ping) the gateway/other hosts:

     # ping 192.168.1.1          (check network connection)
   
    #ping www.google.com    (check Internet connection )

IF You want to assign temporary ip address then Log on as root user and run the below command.
#ifconfig eth0:0 192.168.1.101 netmask 255.255.255.0
#ifconfig eth0:1 192.168.1.102 netmask 255.255.255.0
