Catalyst 9000系列交换机上的EVPN VXLANv6故障排除
目录
简介
本文档介绍如何对Catalyst 9000系列交换机上的EVPN VXLANv6进行故障排除。
先决条件
要求
Cisco 建议您了解以下主题：
- 单播EVPN VxLAN功能、BGP和MVPN（组播虚拟专用网络）。
- IPv4和IPv6单播
- 组播概念和组播如何运行
使用的组件
本文档中的信息基于以下软件和硬件版本：
- Catalyst 9000 系列交换机
注:9200、9500X和9600X不支持VXLANv6
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
术语
| EVPN |
以太网虚拟专用网络 |
|
| VXLAN |
虚拟可扩展LAN（局域网） |
VXLAN旨在克服VLAN和STP的固有局限性。推荐的IETF标准[RFC 7348]提供与VLAN相同的以太网第2层网络服务，但灵活性更高。功能上，它是MAC-in-UDP封装协议，在第3层底层网络上作为虚拟重叠运行。 |
| VTEP |
虚拟隧道终端 |
这是执行封装和解封的设备 |
| EVI |
EVPN实例 |
EVPN实例(EVI)由虚拟网络标识符(VNI)表示。EVI表示PE路由器上的VPN。它充当IP VPN路由和转发(VRF)的相同角色，并且EVI被分配了导入/导出路由目标(RT) |
| NVE |
网络虚拟接口 |
进行封装和解封的逻辑接口 |
| VNI |
VXLAN网络标识符 |
唯一标识每个第2层子网或网段。VNI有两种类型： 对称(L2VNI):VTEP具有相同的VNI 非对称(L3VNI):VTEP没有相同的VNI并通过单个公共VNI路由。 |
| BUM |
广播、未知单播、组播 |
BUM流量通过与NVE配置下的VNI关联的Mcast组发送。 |
| TRM |
租户路由组播 |
基于BGP-EVPN的解决方案，可在VxLAN交换矩阵中连接到VTEPS的源和接收器之间启用组播路由[RFC7432]。L2TRM（第2层TRM）和L3TRM（第3层TRM）有两种类型 |
| MDT |
组播分布树 |
在VTEP之间构建的组播树，用于租户组播流量的封装和隧道。 |
| PVLAN |
专用VLAN |
将VLAN的以太网广播域划分为子域，这样您就可以将交换机上的端口彼此隔离。 |
| MIB |
管理信息库 |
A 简单网络管理协议(SNMP)监控器对象 |
| PIM-BIDIR |
协议无关组播双向 |
一种PIM，其中流量仅沿着共享树转发 根植于组的交汇点(RP)。 |
| VFI |
虚拟转发实例 |
虚拟网桥端口，能够根据目的MAC地址、源MAC地址学习和老化等执行本地桥接功能，例如转发。 |
| IRB |
集成路由和桥接 |
启用第2层VPN和第3层VPN重叠，允许重叠中的终端主机在同一子网内和VPN内的不同子网之间相互通信。 |
| IMET |
包含组播以太网标记 |
也称为BGP路由类型3(RT3)，用于自动发现远程对等体，以便在VXLAN上设置BUM隧道。IMET路由承载从远程对等体通告的远程（出口）VNI，这可能与本地VNI不同。这些远程VNI称为下游分配的VNI。 |
| DAG |
分布式任播网关 |
所有VTEP的默认网关功能。相同的网关IP存在于所有VTEP上，并允许交换矩阵中的移动性。 |
| IR(B) |
集成路由（和桥接） |
启用第2层VPN和第3层VPN重叠，允许重叠中的终端主机在同一子网内和VPN内的不同子网之间相互通信。 |
| RNH |
远程下一跳 |
远程VTEP |
| RPF |
反向路径转发 |
返回到源的单播路径。 除非收到的组播数据包与单播路由表路径相同，否则不会接受/转发传入组播数据包。（“ip multicast multipath”使用案例已排除）。 |
| RP |
汇集点 |
设备在PIM稀疏模式下执行的角色。组播源和接收器的公共会议点。 |

绿地EVPN VXLANv6拓扑
验证（绿地或双堆栈）
在执行每流量故障排除之前，必须先验证EVPN VXLANv6拓扑级别信息，以确保正确运行。本部分显示两个部署的验证命令，并根据您的部署选择适用的验证命令。
底层连接
验证VTEP和主干之间的IPv6底层连接（对于绿地VXLANv6，您只需要验证IPv6底层连接）。

注意：注意：对于双下一跳IMET路由，EVI导入路由中的PMSI隧道属性将其主要下一跳地址用作隧道标识符。如果本地优先级是隧道封装下一跳地址系列的本地优先级，则BGP会使用隧道封装属性中的辅助下一跳地址替换此优先级。在本示例中，虽然BGP将隧道终端显示为10.2.2.2，但安装到L2RIB时，它替换为2001:DB8:2::2。这是因为BGP不会更改属性表中的属性条目。

BUM流量转发（组播复制）
本部分提供了一个示例，用于排除EVI 2中从VTEP1到VTEP2的BUM流量故障，在该示例中，复制类型配置为静态。
在两个VTEP上的EVPN管理器中，验证EVI的复制类型是否设置为静态
-
两个VTEP必须为同一EVI配置相同的底层组播组。底层组播组信息来自NVE。如果NVE接口配置未正确设置，请选中它。

VTEP之间的单播转发（通过L2VNI的相同VLAN）
本节提供单播流量故障排除的示例：
- 从主机H11连接到VLAN 11上的VTEP1（MAC地址为aabb.0000.0011和IP 192.168.11.11）
- 连接到VLAN 11上VTEP3的主机H31（MAC地址为aabb.0000.0031,IP地址为192.168.11.31）。
验证源主机上已解析目的IP地址的ARP
-
ARP数据包在EVPN交换矩阵中作为BUM流量的一部分处理。如果主机上的ARP未解析，请使用故障排除步骤将EVPN BUM流量转发到您的网络中使用的相应已配置复制类型。

VTEP之间的单播转发（通过L3VNI的不同的VLAN）
本节提供单播流量故障排除示例
- 从主机H11连接到VLAN 11上的VTEP1（MAC地址为aabb.0000.0011和IP 192.168.11.11）
- 连接到VLAN 12上VTEP2的主机H22（MAC地址为aabb.0000.0022,IP地址为192.168.12.22）
验证主机上已解析默认网关的ARP

边界枝叶和MPLS VPN路由器之间的EVPN切换
本节适用于L3VPN切换和多VRF切换(VRF lite/PE-CE)
检验通告给EVPN交换矩阵中边界枝叶(vtep3)的远程VPN路由器(R1)上的IP前缀
- VPN节点R1有一个MPLS底层，它是一个单堆栈。Border-leaf节点Leaf3和EVPN交换矩阵的其余部分可以处于单堆栈或双堆栈模式，
如果EVPN路由类型5(RT5)存在流量问题，请检查以下内容：
步骤1:确认RT5路由在EVPN全局表中
第二步： 验证路由是否已导入VRF
- 必须为VRF配置导入RT。
- 在边界枝叶/边界主干上为切换场景拼接路由目标(RT)
- 确保BGP EVPN配置“advertise l2vpn evpn”存在于地址系列vrf中
- 确保在地址系列l2vpn evpn和vpnv4/vpnv6错误L3VPN切换（在边界节点上）上完成正确的导入配置，如下所示：

第三步： 使用此命令检查本地VTEP状态
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
第四步： 检查是否已为VRF安装远程下一跳(RNH)。
- RNH可确保安装在RIB中的路由的邻接关系。
- BGP在BGP VPN表中安装RT5路由，然后将其安装在相应的VRF IP表中。
- 远程VTEP的参数（例如RMAC、eVNI和RTEP）可确保已安装的nexthop的邻接关系。RTEP与路由的下一跳地址相同。
- BGP直接在L3-EVPN/NVE中安装RNH。
当RNH不正确时，路由的CEF条目将具有不完整的邻接关系。
- 在双堆栈方案中，您需要检查路由的下一跳和RNH RTEP（远程隧道终端）是否相同。
当路由未安装或安装的路由具有不完整的邻接关系时，请检查RNH参数并与本地节点中的配置和路由中的参数值相关联。
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.F600 / 2001:DB8:2::2 / yes]
[30000 / AABB.CC81.F500 / 2001:DB8:1::2 / yes]
第5步：检查NVE对等体状态
- 当BGP收到来自远程对等体的路由并正确安装到RIB和L3-EVPN/NVE子系统时，NVE对等体状态为打开。
VTEP3#show nve peers
