l3vpn-MPLS
آموزش راه اندازی l3vpn-MPLS در سودار
توضیح سناریو
در سناریوی زیر provider در core شبکه خود از mpls استفاده می کند و customer ها نیز در شبکه خود از ospf استفاده می کنند . هر customer می خواهد با استفاده از بستر mpls شبکه provider ارتباط بین شبکه (شعب) خود را برقرار کند . provider در روتر های PE خود برای هر customer یک vrf در نظر می گیرد و اینترفیس مربوط به هر customer را در vrf مخصوص به customer قرار می دهد . پس از آن با استفاده از MP-BGP ارتباط vpn بین همه PE ها برقرار می کند . در این vpn بسته های هر customer دارای tag مشخص می باشد که این تگ ها در شبکه core تفسیر نمی شود و فقط به سمت PE ارسال می شود در PE با توجه به tag ، بسته ها به سمت customer مورد نظر forward می شوند . بدین ترتیب چند customer می تواند بصورت جداگانه و بدون ارتباط با دیگر customer ها از شبکه provider استفاده نماید .
در ادامه تنظیمات همه روتر ها را مشاهده می کنید

نکته
در جدول Route در روتر های PE مشاهده می شود که برای customer1 , customer2 جدول های route جداگانه وجود دارد و مسیریابی این دو از یکدیگر جدا است . این مسئله در جدول route روترهای (C1E1,C1E2,C2E1,C2E2) CE نیز قابل مشاهده است که در جدول هر کدام مسیرهای مربوط به شبکه خود را دارند .
