Tarkvara paigaldamine
Quagga tarkvara paigaldamiseks tuleb öelda
# apt-get install quagga
Kataloogis /etc/quagga peavad asuma seadistusfailid.
Ruuterite seadistamine
Enne Quagga tarkvara seadistamist tuleb ruuterite võrguseadmed seadistada. Seejärel moodustada kummaski arvutis sellise sisuga /etc/quagga/ospfd.conf seadistusfailid.
Peakontor
/etc/quagga/ospfd.conf sisu võiks olla nt selline
hostname ospfd password zebra log stdout ! interface eth1 ! interface eth2 ! router ospf ospf router-id 192.168.14.14 redistribute connected network 192.168.15.0/24 area 0.0.0.0 network 192.168.16.0/24 area 0.0.0.0 ! line vty

/etc/quagga/ospfd.conf sisu võiks olla nt selline
hostname ospfd password zebra log stdout ! interface eth1 ! interface eth2 ! router ospf ospf router-id 192.168.17.17 redistribute connected network 192.168.15.0/24 area 0.0.0.0 network 192.168.16.0/24 area 0.0.0.0 ! line vty
Quagga käivitamiseks tuleb öelda
# /etc/init.d/quagga start Loading capability module if not yet done. Starting Quagga daemons (prio:10): zebra ospfd2009/06/09 20:28:44 OSPF: ASBR[Status:1]: Update
Ruuteri haldusliidese kasutamine
Quagga ruuterist endast saab ruuterit hallata vtysh programmiga, liides on sarnane Cisco IOS'ile.

Antud OSPF kasutusjuhtumil pakub huvi kontrollida, milliseks on ruutingud kujunenud, kirjutades 'show ip ospf ?' saab näha võimalikke asjakohaseid käske
quagga-router# show ip ospf ? <cr> border-routers for this area database Database summary interface Interface information neighbor Neighbor list route OSPF routing table
Nt küsides naabrite nimekirja
quagga-router# show ip ospf nei Neighbor ID Pri State Dead Time Address Interface RXmtL RqstL DBsmL 10.0.14.1 1 Full/Backup 33.406s 192.168.15.254 eth1:192.168.15.1 0 0 0 10.0.14.1 1 Full/Backup 33.406s 192.168.16.254 eth2:192.168.16.1 0 0 0

Operatsioonisüsteemi juurkasutajana ruutingutabelit küsides saab veenduda, et Quagga tõepoolest modifitseerib ruutingutabelit
