Installing And Configuring OSPF protocol on Ubuntu 10.04

This tutorial is for those who are interested in installing and configuring OSPF protocol on Ubuntu 10.04
I will try to make this tutorial as easy as possible.
To move on I will put them down as steps that should be followed one by one in successful accomplishment of the above said task.
To begin with I will assume you have installed Ubuntu 10.04 which is completely updated.
Now goto your Ubuntu software center and search for ospf , you will see something like this

As you can see I have installed the ospf routing deamon.

Now open Terminal , and start putting in these commands, which are as follows:

#sudo su

#nano /etc/quagga/daemons

Edit it like this,

zebra=yes

bgpd=no

ospfd=yes

ospf6d=no

ripd=no

ripngd=no 

Save it and close it, and keep going!

#cp /usr/share/doc/quagga/examples/zebra.conf.sample /etc/quagga/zebra.conf

#cp /usr/share/doc/quagga/examples/ospfd.conf.sample /etc/quagga/ospfd.conf

#cp /usr/share/doc/quagga/examples/vtysh.conf.sample /etc/quagga/vtysh.conf

#nano /etc/quagga/debian.conf

Edit it like this,

# If this option is set the /etc/init.d/quagga script automatically loads 

# the config via "vtysh -b" when the servers are started. 

# Check /etc/pam.d/quagga if you intend to use "vtysh"! 

# 

vtysh_enable=yes 

zebra_options=" --daemon -A " 

bgpd_options=" --daemon -A " 

ospfd_options=" --daemon -A " 

ospf6d_options="--daemon -A " 

ripd_options=" --daemon -A " 

ripngd_options="--daemon -A " 

isisd_options=" --daemon -A " 

Save it - Exit, and keep moving forward,

#nano /etc/quagga/vtysh.conf

Edit it like this,

!

! Sample

!

! service integrated-vtysh-config

hostname quagga-router

username root nopassword

!

Save it,Exit - Keep moving !

#nano /etc/quagga/ospfd.conf

Edit it like this,

! Zebra configuration saved from vty

!   2012/03/10 05:06:34

!

hostname ospf

password zebra

enable password zebra

!

!

!

interface eth0

!

interface eth1

!

interface lo

!

router ospf

network 192.168.10.101/24 area 0.0.0.0 /* This was IP Address on eth1 - You should put your own*/

!

line vty

!

Save,Exit - Move on bro !

#echo VTYSH_PAGER=more > /etc/environment

#echo "1" > /proc/sys/net/ipv4/ip_forward

#echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf

Log out and log back in !

Open the terminal and get to work !

#sudo su

#chown quagga.quaggavty /etc/quagga/*.conf

#chmod 640 /etc/quagga/*.conf

#/etc/init.d/quagga restart

#vtysh - c "write" ( save all your configuration )

#vtysh - c "show ip forwarding" ( this should indicate as being on if its correctly done )

#vtysh - c "show ip route" ( this should tell you that your ospf is working via ethX )

#vtysh - c "show ip opsf neighbor" ( shows the neighbor if any )

#vtysh - c "show ip ospf database" ( shows the entire activity )
