Bu Lab’daki amacım OSPF’in genel bir tekrarını yapmak olacak. Komutları uzun uzun yazıyor olacağım.

Aşağıdaki topolojiyi uygulayacağım.

ospf

Bu Lab’da istenilenler topolojinin sol üst köşesinde yazıyor.

Buna göre;

1- İlk olarak router interfacelerine ve VPC’lere sırasıyla IP’lerini vererek başlıyorum.

4- Passive Interfaceleri ayarla. Routerlarda çok fazla interface var, bundan dolayı sadece birer tane olacak şekilde kısa kısa göstereceğim. Burada “Hello” paketlerinin gitmesini istemediğimiz interfaceleri pasif konuma getiriyoruz.

R1:

R1(config-router)#exit

R20(config-router)#exit

R21:

R21(config)#router ospf 1

R21(config-router)#exit

5- R6 Router’ı üzerinde Default Route yaz. Bunun anlamı; bilmediğin her rotayı ona sor. Yani Default Gateway’e sor. Ben burada örnek olması için farklı Autonomous System olan R7’nin Interfacesini yazacağım

R6:

R6(config)#ip route 0.0.0.0 0.0.0.0 172.16.1.2

6- Default Route’u yayınla.

R6:

R6(config-router)#exit

7- SHA512 Authentication yapılandır.

8- Virtual Link Yapılandır (R16-R5) (R3-R17) (R2-R19) (R4-R20) Virtual link yapmamızın amacı Area 0’a doğrudan bağlantısı olmayan areaların sanal bir link ile bağlanmasını sağlamak. Peki Area 0’a doğrudan bağlı olmayan arealara ne olur? Örneğin Virtual Link olmadan R21 Router’ının routing tablosuna bakalım:

ospf

Hiçbir şey yok. Yani bu router diğer networklere gidemez. Bir de yaptıktan sonra tekrar bakalım.

Virtual Link 1 R16:

R16(config)#router ospf 1
R16(config-router)#area 5 virtual-link 5.5.5.5
R16(config-router)#exit

R5:

R5(config)#router ospf 1
R5(config-router)#area 5 virtual-link 16.16.16.16
R5(config-router)#exit

Virtual Link 2 R17:

R17(config)#router ospf 1
R17(config-router)#area 5 virtual-link 3.3.3.3
R17(config-router)#exit

R3:

R3(config)#router ospf 1
R3(config-router)#area 5 virtual-link 17.17.17.17
R3(config-router)#exit

Virtual Link 3 R2:

R2(config)#router ospf 1
R2(config-router)#area 6 virtual-link 19.19.19.19
R2(config-router)#exit

R19:

R19(config)#router ospf 1
R19(config-router)#area 6 virtual-link 2.2.2.2
R19(config-router)#exit

Virtual Link 4 R4:

R4(config)#router ospf 1
R4(config-router)#area 6 virtual-link 20.20.20.20
R4(config-router)#exit

R20:

R20(config)#router ospf 1
R20(config-router)#area 6 virtual-link 4.4.4.4
R20(config-router)#exit

Şimdi de yine örnekten devam ederek R21 Router’ının routing tablosuna bakalım.

ospf

Görüldüğü gibi artık bir hayli route birden eklenmiş oldu. Artık diğer networklere erişebilir hale geldi. Virtual-Link yapmanın amacı budur.

R21’de bazı networklere gitmek için 2 rota görünüyor bir tanesi 81.1’den diğeri ise 80.1’den. Bu durumda OSPF yük dengeleme yapacaktır. Eğer istersem bu rotalardan birini önceliklendirebilirim. Eğer ki illa R19’dan değil de R20’den gitsin istersem R21’in interfacesi altında cost değeriyle oynayarak bunu yapabilirim. Örnek olarak yapalım. Yukarda görüldüğü üzre 10.0.0.0/24 networküne giden iki rotanın da Cost değeri 400. OSPF en düşük Cost değerindeki interfaceden paketi gönderir. Bundan dolayı e0/0 interfacesine Cost değeri olarak 2, e0/1 interfacesine de 1 Cost değeri verirsem olay tatlıya bağlanır. Unutulmamalıdır ki bu değişiklik, ilgili interfacelerden gidilen diğer rotaları da etkileyecektir. Başlayalım,

R21:

R21(config)#interface e0/1
R21(config-if)#ip ospf cost 1
R21(config-if)#int e0/0
R21(config-if)#ip ospf cost 2
R21(config-if)#exit

Şimdi route tablosuna tekrar bakalım.

ospf

Dediğim gibi tabloda da bir hayli değişiklik olmuş oldu.

Devam edelim.

9- R6 ve R7 Router’ları üzerinde EIGRP yapılandır.

Başka Dynamic Routing protokolü kullanan networklerle iletişim kurmak için Redistribution yapmamız gerek. Örnek olarak ben bu topolojide R7 adında bir Router oluşturdum ve burada da EIGRP koşturacağım. Daha sonra da OSPF-EIGRP Redistribution yapılandıracağım. Bunun için R7’de basit bir şekilde EIGRP konfigürasyonu yapıyorum.

R7:

R7(config)#router eigrp 100
R7(config-router)#network 192.168.1.1 0.0.0.0
R7(config-router)#network 172.16.1.2 0.0.0.0
R7(config-router)#exit

Şimdi R6’da da yine aynı şekilde bir de EIGRP protokolü çalıştıracağım. Bu sayede Redistribution yapabiliyor olacağım. EIGRP çalıştırırken AS numarasının aynı olması gerekmektedir. Aksi halde komşuluk kurulmaz. R7’de 100 olarak yapılandırdım. Aynı şekilde R6’da da 100 olarak yapılandırıyorum.

R6:

R6(config)#router eigrp 100
R6(config-router)#net
R6(config-router)#network 172.16.1.1 0.0.0.0
R6(config-router)#exit

10- Redistribution yap (EIGRP). Şimdi sıra tabloları aktarıp döndermekte.

R6:

R6(config)#router eigrp 100
R6(config-router)#redistribute ospf 1 metric 10000 1000 255 1 1500
R6(config-router)#exit
R6(config)#router ospf 1
R6(config-router)#redistribute eigrp 100 metric 66 metric-type 1 subnet tag 555

11- Test et. Son olarak en uç cihazlardan birkaç ping testi yapalım.

VPC3’den R21 Loopback IP’sine (10.0.110.1) VPC3:

VPCS> ping 10.0.110.1
84 bytes from 10.0.110.1 icmp_seq=1 ttl=251 time=5.771 ms

VPC2’den R7’nin Loopback IP’sine (192.168.1.1) VPC2:

VPCS> ping 192.168.1.1
84 bytes from 192.168.1.1 icmp_seq=1 ttl=252 time=4.994 ms

84 bytes from 192.168.1.1 icmp_seq=5 ttl=252 time=5.089 ms

Artık bütün networkler birbirlerine gidebildiğine göre Lab başarıyla tamamlanmıştır.

Teşekkürler,

İyi Çalışmalar.
