Quagga Case 3 - OPSF Adv
http://openmaniak.com/quagga_case3.php
1. CASE PRINCIPLE
We will test in this third example a medium difficulty level environment where two routers (Cisco 3750 & Quagga B) are linked together with two OPSF areas, one OSPF area is tagged as stub area.
The Quagga B router and the Cisco 2651 are located in a stub area. They have OPSF intra(O) and inter-area routes (OIA) in their routing tables but no external OSPF route. To route these external OPSF networks like 10.200.1.1 (see next paragraph), there is a
default OSPF route to the border router (Quagga A router) on the routers inside area 1.
Quagga A is a border router because it is in area 0 or backbone area and in area 1.
For the purpose of our case study, the 10.200.1.1 static route is redistributed into OSPF on the Quagga A router to "artificially" create an external OPSF network tagged as OE2. Because of the stub area, this network should not be propagated on the Quagga B
router and the Cisco 2651.

You must set your Linux system correctly to launch Quagga successfully. See the Quagga tutorial for help about this. |

Check that the zebra and ospfd daemons are activated:
#vim /etc/quagga/daemons |
bgpd=no
ospfd=yes
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 ospfd.
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.
