تسعى مجموعة الوثائق لهذا المنتج جاهدة لاستخدام لغة خالية من التحيز. لأغراض مجموعة الوثائق هذه، يتم تعريف "خالية من التحيز" على أنها لغة لا تعني التمييز على أساس العمر، والإعاقة، والجنس، والهوية العرقية، والهوية الإثنية، والتوجه الجنسي، والحالة الاجتماعية والاقتصادية، والتمييز متعدد الجوانب. قد تكون الاستثناءات موجودة في الوثائق بسبب اللغة التي يتم تشفيرها بشكل ثابت في واجهات المستخدم الخاصة ببرنامج المنتج، أو اللغة المستخدمة بناءً على وثائق RFP، أو اللغة التي يستخدمها منتج الجهة الخارجية المُشار إليه. تعرّف على المزيد حول كيفية استخدام Cisco للغة الشاملة.
ترجمت Cisco هذا المستند باستخدام مجموعة من التقنيات الآلية والبشرية لتقديم محتوى دعم للمستخدمين في جميع أنحاء العالم بلغتهم الخاصة. يُرجى ملاحظة أن أفضل ترجمة آلية لن تكون دقيقة كما هو الحال مع الترجمة الاحترافية التي يقدمها مترجم محترف. تخلي Cisco Systems مسئوليتها عن دقة هذه الترجمات وتُوصي بالرجوع دائمًا إلى المستند الإنجليزي الأصلي (الرابط متوفر).
يوضح هذا المستند كيفية التحقق من بث SD-Access (SDA) الأصلي.

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.
هذا وثيقة يستطيع أيضا كنت استعملت مع هذا جهاز وبرمجية صيغة:
البث المتعدد الأصلي ل SDA هو شكل من بث متعدد تراكب، يتم إستخدامه لحمل حركة مرور البث المتعدد بين أجهزة البنية، بتضمين حركة مرور البث المتعدد في مجموعة بث متعدد أخرى. يمكن للبث المتعدد الأصلي توجيه حركة مرور البث المتعدد بين المصادر وأجهزة الاستقبال التي تكون إما في شبكة VLAN نفسها أو شبكة VLAN مختلفة (يمكن توجيه البث المتعدد لشبكة VLAN نفسها). لا تتم إعادة توجيه حركة مرور البث المتعدد بين المصادر والاستلام على حافة البنية (FE) نفسها باستخدام بث متعدد عبر الشبكة المحلية الظاهرية (VXLAN)، ولكن يتم توجيهها محليا بواسطة FE. لا يمكن للبث المتعدد الأصلي توجيه حركة مرور البث المتعدد للمجموعات التي تطابق 224.0.0.0/24 أو مدة البقاء (TTL) = 1، ويتم معالجة هذه البيانات عبر غمر الطبقة 2 (L2). يمكن تكوين البث المتعدد الأصلي لإعادة توجيه أي بث متعدد مصدر (ASM) أو بث متعدد محدد المصدر (SSM) أو مجموعة من كليهما. تعتمد البث المتعدد الأصلي على البث المتعدد الأساسي.
ملاحظة: يمكن أن تختلف أوامر النظام الأساسي (Fed). يمكن أن يكون الأمر show platform fed <active|standby>" مقابل "show platform fed switch <active|standby>". إذا لم يتم توزيع الصياغة المشار إليها في الأمثلة، فيرجى تجربة المتغير.

يتم التحقق من البث المتعدد المستقل للبروتوكول (PIM) في هذا القسم، بدءا من التحقق من إنشاء (S،G) على موجه الخطوة الأولى (FHR)
يرسل مصدر البث المتعدد، 10.47.7.3، حزم بث UDP المتعدد إلى 239.0.0.5. التحقق من تعقب جهاز IP (IPDT)، وإعادة التوجيه السريع من Cisco (CEF)، وإعادة توجيه المسار العكسي (RPF)، يشير بشكل صحيح نحو مصدر البث المتعدد. وبالإضافة إلى ذلك، تأكد من أن AnyCast Gateway SVI هو الموجه المعين من PIM (DR) لهذا المقطع.
أستخدم الأمر show device-tracking database address <ip address>" لضمان وجود إدخال IPDT صالح

لمنع هذا، تعامل مع مصدر البث المتعدد كمضيف صامت، حيث يتم توجيه بث IP، وفيضانات، يمكن أن تتغلب روابط ISF/IPDT الثابتة على هذه المشكلة.
تسجيل PIM هو تدفق حزمة البث الأحادي، والذي يستخدم LISP/VXLAN مثل أي حزمة أخرى للبث الأحادي. هناك العديد من المتطلبات للتحقق من أن FHR يمكن تسجيل مصدر البث المتعدد بشكل صحيح إلى AnyCast RP.
أولا، تأكد من تكوين RP AnyCast بشكل صحيح ل GDA.
