Merhaba,
Özellikle datacenter lar için işe yarayabilecek olan vxlan teknolojisinden bahsetmek istiyorum. Vxlan en temel hali ile iki farklı lokasyondaki vlanları tek bir çatı altındaymış gibi çalıştırmanızı sağlıyor. Bunun için Dell tarafında lisanslama maliyeti de yok. Peki bu ne işe yarar derseniz öncelikle klasik mimaride ne yapıyoruz onu anlatmak gerekiyor sanıyorum. Eğer çalıştığınız kurumun birden fazla lokasyonu var ise ve siz IT ekibindenseniz bilirsiniz ki her bir lokasyon için, firewall, bu lokasyonların merkeze bağlantısı için vpn yada mpls data hatları ve bir çok farklı lokasyonda bulunan her bir sorun için ayrı ayrı vpn bağlantılar ile soruna müdahale etmek gerekiyor. Vxlan ise bunun yerine tüm dış lokasyonları merkeze bağlıyor. Dolayısıyla merkezde bulunan 10,100,4000 vs gibi numaralandırdığınız vlanlarınıza şubeleriniz de dahil oluyor. Sonucunda şubede bir uygun maliyetli internet hattı ve switch ile merkezden hem kendi bilgisayarınızı örneğin vlan 10 da tutabiliyor hemde Ankara’ daki şubenizi aynı vlanda bulundurabiliyorsunuz. Yönetim tarafında ne gibi kolaylıklar getireceğini siz düşünün. Sıklıkla datacenter tarafında kullanılan bu teknolojinin alt yapısı uzun süredir noktadan noktaya metro ethernet hatları ile yapılıyordu. Şimdi ise bu kiralamaya ve maliyete gerek kalmadan bir kez yaptırılacak bir yatırım ile bunu kullanmak mümkün.
Vxlan nasıl çalışara en güzel örnek aşağıdaki görselde yer alıyor.
Kısaca bundan aklımdayken bahsetmek istedim. Yakın zamanda bu yazımı “Nasıl yapılır” dokümanına çevirmeyi hedefliyorum. Fakat şimdi biraz işe dönmeliyim 🙂

Çok geç kalınmış bir güncelleme, işte s3048 ve s4048 ler ile İstanbul – Ankara ofis senaryosuna göre çalışan bir konfigürasyon örneği, eğer kullanmak isterseniz bu konfigürasyona vlan larınızı eklemek yeterli
