Quagga Case 1 - static Routing
http://openmaniak.com/quagga_case1.php
1. CASE PRINCIPLE
In this first case study, we will see a very simple example where the routing is done with only static routes.
 |
Functionalities tested: Interface settings Static routes
Telnet access |
 |
You must set your Linux system correctly to launch Quagga successfully. See the Quagga tutorial for assisstance. |
LINUX CONFIGURATIONSCheck that the zebra daemon is activated:
| #vim /etc/quagga/daemons |
bgpd=no
ospfd=no
ospf6d=no
ripd=no
ripngd=no
isisd=no
If you changed your daemons file, restart the quagga service:
| #vim /etc/init.d/quagga restart |
Removing all routes made by zebra.
Nothing to flush.
Loading capability module if not yet done.
Starting Quagga daemons (prio:10): zebra.
Set the Quagga A hostname in the /etc/quagga/vtysh.conf file:
| #vim /etc/quagga/vtysh.conf |
! Sample
!
! service integrated-vtysh-config
hostname Quagga_A
username root nopassword
!
Set the Quagga B hostname in the /etc/quagga/vtysh.conf file:
| #vim /etc/quagga/vtysh.conf |
! Sample
!
! service integrated-vtysh-config
hostname Quagga_B
username root nopassword
!
Don't forget to activate the ip forwarding on the Quagga A router!
It is not necessary to activate ip forwarding on the Quagga B router because it has only one network interface.
