    本檔案介紹如何在多站點環境中對乙太網路VPN/虛擬可擴充區域網路(EVPN/VxLAN)進行疑難排解。

    This paper describes how the Ethernet VPN/ Virtual Extendable Area Network (EVPN/VxLAN) is difficult to solve in multi-site settings.

    思科建議您瞭解以下主題：

    Cisco suggests that you should be aware of the following themes:

    • 多重協定標籤交換(MPLS)第3層VPN
    • 多重通訊協定邊界閘道通訊協定(MP-BGP)
    • EVPN

    Topology

    本檔案介紹流量源自哪裡(DC-1，主機1/2 - 172.20.2.10/11)，然後使用我們的封包前往目的地DC-2，主機4(172.20.2.100)。

    This document describes the origin of the traffic (DC-1, host 1/2 - 172.20.2.10/11) and then uses our envelopes for destination DC-2, host 4(172.20.2.100).

    流量傳輸： Control-Plane_Traffic_Flow_v4步驟1.在源節點上檢查正確的IP和VLAN。

    Flow transfer:   

    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#

     現在，您可以從源節點連線到其SVI-GW的Vlan-1000。

    & nbsp; now you can connect from the source node to its SVI-GW 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#

    步驟2.轉到leaf1的第一跳，在第2層和第3層驗證內容。

    Step 2. Move to the first jump of leaf1 to verify content on the 2nd and 3rd levels.

    現在檢視leaf1是否從源節點獲取mac和arp。

    Now check if leaf1 gets mac and arp from the source node.

    是，在eth1/23上通過Vlan1000獲知源節點的mac-address(0035.1ac1.37c2)和IP 172.20.2.10。

    Yes, mac-address (0035.1ac137c2) and IP 172.20.2.10 at eth1/23 via Vlan1000 source node.

    This shows how Leaf1 has access to the IP/mac entry to generate the source node.

    一旦您驗證了leaf1中的mac/IP條目的生成方式，這就是mac/mac-ip資訊與BGP繫結並被通告為l2vpn/evpn路由的重要觀察點之一。

    Once you have verified the mac/IP mode of generation in leaf1, this is one of the important observations that the mac/mac-ip information binds to the BGP and is notified as the l2vpn/evpn route.

    在DC-1的BORDER層進行檢驗，路由將從該層傳播到其他站點。

    Tests will be carried out on the Border floor of DC-1 and routers will be disseminated from that floor to other sites.

    然後，您可以看到在BGW-1中交換了哪些路由、哪些路由型別以及有多少路由

    Then you can see which routes are exchanged in BGW-1, which are different and how many.

    現在，您可以瞭解如何在N5K上捕獲資料包，讓我們在N9K上放大。Data-Plane_N9K_Traffic_Flow-2_v1

    Now, you can understand how to capture the data package on N5K, allowing us to zoom in on N9K.

    您可以從Host-4開始，對Host-2執行簡單ping。雖然這是LEAF交換機的中轉流量，但仍然檢查您是否能夠正確處理這些資料包。在DC-1/Leaf-2確認。

    You can run a simple ping on Host-2 starting with Host-4. Although this is a LEAF switch flow, you can still check if you can handle the data packages correctly. Confirm at DC-1/Leaf-2.

    為了進行確認，請監控介面eth-1/23，並將這些資料包推到CPU並運行ethanalyzer/dmirror進行確認。

    For purposes of verification, monitor the interface eth-1/23 and forward the kits to the CPU and run the ethanalyzer/dmirror for validation.

    如果要從源傳送某些資料並在目標枝葉上捕獲，請執行以下步驟：

    If you want to send some data from the source and catch it on the target branch, do the following:

    1. 啟動從Host-4到Host-2的ping。
    2. 來源：172.20.2.100 //源MAC地址：00:C8:8B:F9:5F:41
    3. 目的地： 172.20.2.11 // Dst MAC地址： E0:D1:73:A4:1D:41
    4. 資料包大小：777
    5. Do-Not-Fragment：是
    6. 資料模式字串：牛肉

    在此範例中，您的封包計數足夠，因此您可以在來源和目的地枝葉上擷取封包。

    In this example, you can take the package from your source and destination branch.
