- config router ospf (ospfd)

ospfd# conf t
ospfd(config)# router ospf
ospfd(config-router)# ospf router-id 172.16.0.200
ospfd(config-router)# redistribute kernel

- Setting IP address Mikrotik

[admin@MikroTik] > ip address add address=172.16.0.204/28 interface=Backbone

- config routing ospf Mikrotik

[admin@MikroTik] > routing ospf set router-id=172.16.0.204
[admin@MikroTik] > routing ospf set distribute-default=never (note, neigbhor sudah aktif)
[admin@MikroTik] > routing ospf set redistribute-connected=as-type-2
[admin@MikroTik] > routing ospf set redistribute-static=as-type-2

- config area & network

[admin@MikroTik] > routing ospf area add area-id=0.0.0.1 name=area1
[admin@MikroTik] > routing ospf network add network=172.16.0.192/28 area=area1

secara basic dan default setting ospf di quangga dan mikrotik sudah selesai, tingal kita lihat statusnya
di Mikrotik dan quangga
Mikrotik ;
[admin@MikroTik] > routing ospf neighbor print
router-id=172.16.0.200 address=172.16.0.204 priority=1 state=”2-Way” state-changes=0 ls-retransmits=0 ls-requests=0 db-summaries=0 dr-id=172.16.0.204 backup-dr-id=0.0.0.0

ups, sepertinya belum full. Check debug ospf pada log ;

[admin@MikroTik] routing> /log print

dari hasil log ada ketidak cocokan hellointerval antara quangga dan Mikrotik.
Check default hellointerval di quangga dan sesuaikan sesuai informasi log yaitu 10

ospfd(config)# int eth0
ospfd(config-if)# ip ospf hello-interval 10
