Quagga Router Tutorial

Here I'm going to start small tutorial Quagga Linux router, JunOS and Cisco Router in GNS3 lab. Quagga and JunOS will run under virtualbox and add to GNS3 lab later. I'll run BGP, OSPF in between those router.

Part one, we'll install Quagga router under ubuntu server on Virtualbox. Here is the process to follow to configuration of quagga router

Part ONE: Installation of Quagga in Ubuntu

1. Install Quagga:

• Update package lists: Before installing Quagga, it's crucial to update the package lists:
  Bash

  sudo apt update 
  

• Install Quagga:
  Bash

  sudo apt install quagga quagga-doc 
  

  This command installs the Quagga routing suite and its documentation.

2. Configure Quagga Daemons:

• Copy sample configuration files:
  
  Bash

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

  This creates configuration files for Zebra (the routing engine) and BGPd (the Border Gateway Protocol daemon) in the /etc/quagga/ directory.

• Edit daemon file:
  
  Bash

  sudo vim /etc/quagga/daemons 
  

  • Uncomment the lines for the daemons you want to enable (in this case, zebra and bgpd):

    zebra=yes
    bgpd=yes 
    

  • Comment out or disable other daemons (e.g., ospfd, ripd) if you don't need them.
  • Save and exit the file.

3. Start Quagga Services:

• Restart Quagga service:
  Bash

  sudo systemctl restart quagga 
  

  This restarts the Quagga service and applies the new configuration.

4. Verify Quagga Status:

• Check Zebra status:
  Bash

  sudo netstat -nlptu | grep zebra
  

  
  You should see Zebra listening on port 2601 (ZAPI).
• Check BGPd status:
  Bash

  sudo netstat -nlptu | grep bgpd
  

  You should see BGPd listening on ports 179 and 2605.

5. Configure BGPd:

• Edit the BGPd configuration file:
  Bash

  sudo vim /etc/quagga/bgpd.conf
  

  • Define your Autonomous System Number (ASN).
  • Configure neighbors (IP addresses of other BGP routers).
  • Configure BGP parameters (e.g., timers, next-hop self).

Important Notes:

• Refer to the Quagga documentation: For detailed information on configuration options and best practices, refer to the official Quagga documentation.

• Security: Always follow security best practices when configuring routing protocols, such as enabling authentication and limiting access to the Quagga configuration files.

This enhanced guide provides a more comprehensive and step-by-step approach to installing and configuring Quagga on Ubuntu.

 

#telnet localhost 2601

#telnet localhost 2605

To configure vtysh

First of all you must create its configuration file as follows:

#sudo cp /usr/share/doc/quagga/examples/vtysh.conf.sample /etc/quagga/vtysh.conf
!service interegrated-vtysh-config
!hostname quagga-router
username root nopassword
Change your desire name in my case

hostname quagga
username root nopassword

For changing the permission and restart the quagga

#sudo chown quagga.quaggavty /etc/quagga/*.conf
#sudo chmod 640 /etc/quagga/*.conf
#sudo service quagga restart

Now enter into the quagga router

#vtysh

You need to add "VTYSH_PAGER=more" setting in your /etc/enviroment file, otherwise you enconter "(END)" blinking in the left-down corner of the screen every time you enter vtysh command and you have to "q" key to continue.

#su -s
#echo VTYSH_PAGER=more > /etc/enviroment

IP Forwarding is transfering packet between network card and linux system use following command 

#sudo -s
#echo "1" > /proc/sys/net/ipv4/ip_forward
#show ip forwarding

IP forwarding is activated.
