التحقق من الاتصال الشامل عبر حزمة SP لتوجيه المقاطع
المحتويات
المقدمة
يصف هذا المستند العملية للتحقق من الاتصال الشامل عبر موفر خدمة توجيه المقطع (SP) باستخدام برنامج Cisco IOS®XR.
المتطلبات الأساسية
المتطلبات
توصي Cisco بأن تكون لديك معرفة بالمواضيع التالية:
- معرفة توجيه IP الأساسي
- معرفة سطر أوامر Cisco IOS و Cisco IOS XR
المكونات المستخدمة
تستند المعلومات الواردة في هذا المستند إلى إصدارات البرامج والمكونات المادية التالية:
- الموجه مع برنامج Cisco IOS XR
- الموجه مع برنامج Cisco IOS
تم إنشاء المعلومات الواردة في هذا المستند من الأجهزة الموجودة في بيئة معملية خاصة. بدأت جميع الأجهزة المُستخدمة في هذا المستند بتكوين ممسوح (افتراضي). إذا كانت شبكتك قيد التشغيل، فتأكد من فهمك للتأثير المحتمل لأي أمر.
معلومات أساسية
الغرض من هذا المستند هو توضيح التكوين الأساسي لإنشاء سحابة توجيه قطاع وكيفية التحقق من الاتصال من نهاية إلى نهاية على موجهات Cisco IOS XR.
