Catalyst 9000系列交換機上的EVPN VXLANv6故障排除
目錄
簡介
本檔案介紹如何對Catalyst 9000系列交換器上的EVPN VXLANv6進行疑難排解。
必要條件
需求
思科建議您瞭解以下主題：
- 單播EVPN VxLAN功能、BGP和MVPN（組播虛擬專用網路）。
- IPv4和IPv6單播
- 組播概念和組播如何運行
採用元件
本文中的資訊係根據以下軟體和硬體版本：
- Catalyst 9000 系列交換器
註:9200、9500X和9600X不支援VXLANv6
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
技術
| EVPN |
乙太網路虛擬私人網路 |
|
| VXLAN |
虛擬可擴充LAN（區域網路） |
VXLAN的用途是克服VLAN和STP的固有限制。建議採用的IETF標準[RFC 7348]提供與VLAN相同的乙太網第2層網路服務，但具有更高的靈活性。功能上，它是UDP內MAC封裝協定，在第3層底層網路上作為虛擬重疊運行。 |
| VTEP |
虛擬通道端點 |
這是負責執行封裝和解除封裝的裝置 |
| EVI |
EVPN例項 |
EVPN例項(EVI)由虛擬網路識別符號(VNI)表示。EVI表示PE路由器上的VPN。它充當IP VPN路由和轉發(VRF)的相同角色，並且為EVI分配了匯入/匯出路由目標(RT) |
| NVE |
網路虛擬介面 |
進行封裝和解除封裝的邏輯介面 |
| VNI |
VXLAN網路識別碼 |
唯一標識每個第2層子網或網段。VNI有兩種型別： 對稱(L2VNI):VTEP具有相同VNI 非對稱(L3VNI):VTEP沒有相同的VNI，且透過單一通用VNI路由。 |
| BUM |
廣播、未知單播、組播 |
在NVE設定下，BUM流量會透過連結到VNI的Mcast群組傳送。 |
| TRM |
租戶路由多點傳送 |
基於BGP-EVPN的解決方案，可在VxLAN交換矩陣中通過VTEPS連線的源和接收器之間啟用組播路由[RFC7432]。有兩種型別：L2TRM（第2層TRM）和L3TRM（第3層TRM） |
| MDT |
多點傳送發佈樹 |
在VTEP之間構建的組播樹，用於租戶組播流量的封裝和通道化。 |
| PVLAN |
專用VLAN |
將VLAN的乙太網路廣播網域分割為子網域，這樣您就可以將交換器上的連線埠彼此隔離。 |
| MIB |
管理資訊庫 |
A 簡單網路管理協定(SNMP)監控器對象 |
| PIM-BIDIR |
通訊協定無關多點傳送雙向 |
一種PIM，其中的流量僅沿著共用樹轉發 該位置位於組的集合點(RP)。 |
| VFI |
虛擬轉送例項 |
虛擬網橋埠，能夠根據目標MAC地址、源MAC地址學習和老化等執行本地橋接功能，如轉發。 |
| IRB |
整合式路由和橋接 |
啟用第2層VPN和第3層VPN覆蓋，允許覆蓋範圍內的終端主機在同一子網內和VPN內的不同子網之間相互通訊。 |
| IMET |
包含型組播乙太網標籤 |
也稱為BGP路由型別3(RT3)，用於自動發現遠端對等點，以便透過VXLAN建立BUM通道。IMET路由傳送從遠端對等點通告的遠端（輸出）VNI，這可能與本地VNI不同。這些遠端VNI稱為下游指派的VNI。 |
| DAG |
分散式任播閘道 |
所有VTEP上的預設網關功能。相同的網關IP存在於所有VTEP上，並允許交換矩陣中的移動性。 |
| IR(B) |
整合路由（與橋接） |
啟用第2層VPN和第3層VPN覆蓋，允許覆蓋範圍內的終端主機在同一子網內和VPN內的不同子網之間相互通訊。 |
| RNH |
遠端下一跳 |
遠端VTEP |
| RPF |
反向路徑轉送 |
返回到源的單點傳播路徑。 傳入組播資料包不會被接受/轉發，除非它們被接收到與單播路由表相同的路徑。（排除「ip multicast multipath」使用案例）。 |
| RP |
集結點 |
裝置在PIM稀疏模式下執行的角色。組播源和接收器的公共會議點。 |

綠地EVPN VXLANv6拓撲
驗證（綠地或雙堆疊）
在執行每個流量故障排除之前，必須首先驗證EVPN VXLANv6拓撲級別資訊，以確保正確操作。本節顯示兩個部署的驗證命令，並根據您的部署選擇適用的驗證命令。
底層連線
驗證VTEP和Spines之間的IPv6底層連線（對於綠地VXLANv6，您只需要驗證IPv6底層連線）。

註：注意：在雙下一跳IMET路由的情況下，EVI匯入路由中的PMSI隧道屬性將其主要下一跳地址作為隧道識別符號。如果本地優先順序是隧道封裝下一跳地址系列的本地優先順序，則BGP會使用隧道封裝屬性中的次要nexthop地址替換該優先順序。在本例中，雖然BGP將通道端點顯示為10.2.2.2，但安裝到L2RIB時，它被替換為2001:DB8:2::2。這是因為BGP不會更改屬性表中的屬性條目。

BUM流量轉送（多點傳送複製）
本節提供從VTEP1到VTEP2的BUM流量在EVI 2中的疑難排解範例，其中複製型別設定為靜態。
在兩個VTEP上的EVPN管理器中，驗證EVI的複製型別是否設定為靜態
-
兩個VTEP必須為同一EVI配置相同的底層組播組。底層組播組資訊來自NVE。如果未正確設定，請檢查NVE介面配置。

VTEP之間的單點傳播轉送（通過L2VNI的相同VLAN）
本節提供單播流量故障排除的示例：
- 從主機H11連線到VLAN 11上的VTEP1（MAC地址為aabb.0000.0011和IP 192.168.11.11）
- 連線到VLAN 11上VTEP3的主機H31（MAC地址為aabb.0000.0031,IP地址為192.168.11.31）。
驗證在源主機上解析了目標IP地址的ARP
-
ARP封包在EVPN光纖中作為BUM流量的一部分處理。如果在主機上未解析ARP，請使用故障排除步驟針對網路中使用的適當已配置複製型別進行EVPN BUM流量轉發。

VTEP之間的單點傳播轉送（透過L3VNI的不同VLAN）
本節提供單播流量故障排除的示例
- 從主機H11連線到VLAN 11上的VTEP1（MAC地址為aabb.0000.0011和IP 192.168.11.11）
- 連線到VLAN 12上VTEP2的主機H22（MAC地址為aabb.0000.0022,IP地址為192.168.12.22）
驗證主機上已解析預設網關的ARP

邊界枝葉與MPLS VPN路由器之間的EVPN切換
本節適用於L3VPN切換和多VRF切換(VRF lite/PE-CE)
驗證通告到EVPN交換矩陣中邊界枝葉(vtep3)的遠端VPN路由器(R1)上的IP字首
- VPN節點R1有一個MPLS底層，它是單個堆疊。邊界枝葉節點Leaf3和EVPN交換矩陣的其餘部分可以處於單堆疊或雙堆疊模式，
如果EVPN路由型別5(RT5)存在流量問題，請檢查以下事項：
步驟 1.確認RT5路由在EVPN全域性表中
步驟 2. 驗證路由是否已匯入VRF
- 必須為VRF配置匯入RT。
- 在邊界枝葉/邊界脊柱上為切換場景縫合路由目標(RT)
- 確保BGP EVPN配置「advertise l2vpn evpn」存在於地址系列vrf中
- 確保在地址系列l2vpn evpn和vpnv4/vpnv6錯誤L3VPN切換（在邊界節點上）上完成正確的匯入配置，如下所示：

步驟 3. 使用此命令檢查本地VTEP狀態
VTEP3#show bgp l2vpn evpn local-vtep vrf red
Local VTEP vrf red:
Protocol: IPv4
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
Protocol: IPv6
RMAC Address: AABB.CC81.F700
VTEP-IP:10.3.3.2
SEC-VTEP-IP:2001:DB8:3::2
VNI: 30000
BDI:Vlan3
步驟 4. 檢查是否已為VRF安裝遠端下一跳(RNH)。
- RNH可確保安裝在RIB中的路由的鄰接關係。
- BGP將RT5路由安裝在BGP VPN表中，然後將其安裝在相應的VRF IP表中。
- 遠端VTEP的引數（例如RMAC、eVNI和RTEP）可確保已安裝的nexthop的鄰接關係。RTEP與路由的下一跳地址相同。
- BGP會將RNH直接安裝在L3-EVPN/NVE中。
當RNH不正確時，路由的CEF條目將具有不完整的鄰接關係。
- 在雙堆疊方案中，您需要檢查路由和RNH RTEP（遠端隧道端點）的下一跳是否相同。
當未安裝路由或安裝的路由具有不完整的鄰接關係時，請檢查RNH引數並與本地節點中的配置和路由中的引數值相關。
VTEP3#show bgp l2vpn evpn rnh vrf red
Remote VTEP entries for vrf red:
Protocol: ipv4
[VNI / RMAC ADDRESS / VTEP-IP / Installed]
[30000 / AABB.CC81.F500 / 2001:DB8:1::2 / yes]
[30000 / AABB.CC81.F600 / 2001:DB8:2::2 / yes]
Protocol: ipv6
[VNI / RMAC ADDRESS / VTEP-IP / Installed]

[30000 / AABB.CC81.F500 / 2001:DB8:1::2 / yes]
第5步：檢查NVE對等體狀態
- 當BGP收到來自遠端對等體的路由並正確安裝到RIB和L3-EVPN/NVE子系統中時，NVE對等體狀態為up。
