أستكشاف أخطاء VRRPv3 ذات الصلة وإصلاحها مع IPv6

المقدمة

يصف هذا المستند الخطوات اللازمة لاستكشاف أخطاء بروتوكول تكرار الموجه الظاهري (VRRPv3) وإصلاحها باستخدام IPv6 في Nexus 9000.

المتطلبات الأساسية

المتطلبات

توصي Cisco NXOS® بأن تكون لديك معرفة بالمواضيع التالية:

• VRRP
• إيثاناليزر
• IPv6
• بروتوكول تكرار الخطوة الأولى (FHRP)

المكونات المستخدمة

يقتصر هذا المستند على أجهزة معينة مثل Nexus 9000.

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

يدعم VRRP الإصدار 2 فقط لعائلة عناوين IPv4، ولكن الإصدار 3 من VRRP (VRRP3) يدعم عائلات عناوين IPv4 و IPv6 على حد سواء. في NX-OS، لا يمكن تمكين كل من VRRP و VRRPv3 على نفس الجهاز. إذا كانت الميزة VRRP ممكنة بالفعل على المحول Nexus Switch، فإن تمكين الميزة VRRPv3 يعرض خطأ يشير إلى تمكين VRRPv2 بالفعل. وبالتالي، يجب إجراء الترحيل من VRRP إلى VRRPv3، والذي له تأثير أقل على الخدمات.

التحقق من الصحة

1) تحقق من التكوين في كلا الجانبين المتطابقين.

المحول 1:

Switch1# show run interface vlan 209

interface Vlan209
no shutdown
no ip redirects
ipv6 address X:X:X:X::70a/125

Switch1#

المحول 2:

Switch2# show run interface vlan 209

interface Vlan209

2) تحقق من ملء جدول عناوين MAC بشكل صحيح.

استكشاف الأخطاء وإصلاحها

سيناريو مكسور.

1) يعرض خيار الأمر show vrrpv3 brief المعلومات المختصرة المتعلقة بالمجموعة، مثل رقم المجموعة، عائلة العنوان، الأولوية، الإستباق، الحالة، العنوان الرئيسي، وعنوان المجموعة (وهو المجموعة الظاهرية IP). في هذا المثال، وكما هو موضح أعلاه، يعد كلا المحولين محولين رئيسيين وهو غير صحيح.

المحول 1:

ومن الناتج أعلاه، يرسل كلا المحولين إعلاناته الخاصة (DEA7 و DE07). وهذا يشير إلى عدم وجود اتصال بين المحولين المشاركين في مجموعة VRRPv3 نفسها.

5) بمجرد حل مشكلة الاتصال التي في هذه الحالة كانت أن واجهة الطبقة 2 كانت في حالة إيقاف عمل على الرغم من أن SVI كان في حالة up، يجب على المحولات الآن عرض الحالة الصحيحة (الأساسي والنسخ الاحتياطي على التوالي) ويتم إرسال الإعلانات فقط بواسطة المحول الأساسي.
