المحتويات
المقدمة
يوضح هذا المستند كيفية أستكشاف أخطاء شبكة Ethernet VPN/ شبكة LAN الموسعة الظاهرية (EVPN/VxLAN) وإصلاحها في بيئة المواقع المتعددة.
المتطلبات الأساسية
المتطلبات
توصي Cisco بأن تكون لديك معرفة بالمواضيع التالية:
- Multiprotocol Label Switching (MPLS) Layer 3 VPN
- بروتوكول العبارة متعدد البروتوكولات-الحدود (MP-BGP)
- EVPN

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.
طوبولوجيا
يوضح هذا المستند مكان إنشاء حركة المرور (DC-1، Host1/2 - 172.20.2.10/11) ثم المشي مع الحزم حتى الوجهة DC-2، Host4 (172.20.2.100).
التحقق من مستوى التحكم
تدفق حركة المرور: 
الخطوة 1. تحقق من IP الأيمن، VLAN على عقدة المصدر.
ToLeaf1#show ip interface brief | exclude down Interface IP-Address OK? Method Status Protocol Vlan1000 172.20.2.10 YES NVRAM up up Vlan1001 172.21.1.10 YES NVRAM up up GigabitEthernet1/0/1 unassigned YES unset up up ToLeaf1#
الآن لديك قابلية الوصول من العقدة المصدر إلى SVI-GW الخاص بها من VLAN-1000.
ToLeaf1#ping 172.20.2.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 172.20.2.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/205/1006 ms ToLeaf1#
الخطوة 2. انتقل إلى الخطوة الأولى التي هي صفحة 1 وتحقق من الأشياء على مستوى الطبقة 2 والطبقة 3.
الآن شاهد ما إذا الورقة 1 تعرف ماك، arp من مصدر عقدة أو لا.
نعم، يتم التعرف على عنوان MAC (0035.1ac1.37c2) و IP 172.20.2.10 لعقدة المصدر في ETH1/23 من خلال VLAN1000.

التحقق من جدول ARP في ورقة المصدر
leaf1#show ip arp vrf all Flags: * - Adjacencies learnt on non-active FHRP router + - Adjacencies synced via CFSoE # - Adjacencies Throttled for Glean D - Static Adjacencies attached to down interface IP ARP Table for all contexts Total number of entries: 5 Address Age MAC Address Interface 172.21.1.10 00:08:14 0035.1ac1.37c3 Vlan1001 172.20.2.10 00:00:58 0035.1ac1.37c2 Vlan1000 10.31.121.1 00:08:14 2c31.24b0.bf46 mgmt0 172.16.1.1 00:07:51 0081.c41c.f007 Ethernet2/23 172.16.2.1 00:08:14 cc46.d68f.d74b Ethernet2/24 leaf1#
هذا يبدي كيف ورقة 1 يحصل الرسالة أن يجعل ip/mac مدخل من مصدر عقدة.
