配置三段式VXLAN实现三层互通示例

配置三段式VXLAN实现三层互通示例

通过配置三段式VXLAN隧道，实现不同数据中心的VM之间三层互通。

组网需求

如图16-23所示，数据中心A和数据中心B规划在不同的BGP AS域，在数据中心内部配置BGP EVPN协议创建分布式网关VXLAN隧道，实现同一数据中心VMa1和VMa2之间的互通、VMb1和VMb2之间的互相通信，通过在Leaf2和Leaf3之间配置BGP EVPN协议创建VXLAN隧道，实现数据中心A和数据中心B之间的互相通信（例如VMa1和VMb2之间互相通信）。

图16-23 配置三段式VXLAN组网图

本示例中interface1，interface2，interface3分别代表GE0/1/0，GE0/2/0，GE0/3/0。

配置思路

采用如下的思路配置跨AS的三段式VXLAN：

  1. 配置各节点IP地址。

  2. 配置IGP实现各节点之间的互通。

  3. 配置静态路由实现数据中心之间的互通。

  4. 在数据中心A和数据中心B内配置BGP EVPN协议创建分布式网关VXLAN隧道。

  5. 在Leaf2和Leaf3上配置BGP EVPN协议创建VXLAN隧道。

数据准备

为完成此配置例，需准备如下的数据：

  • VM所属的VLAN ID。

  • 广播域BD ID。

  • 关联BD的VNI ID和VPN实例下的VNI ID。

操作步骤

  1. 配置各节点接口的IP地址及Loopback接口的地址

    具体配置过程请参考配置文件。

  2. 配置IGP，本示例使用OSPF

    具体配置过程请参考配置文件。

  3. 配置静态路由实现数据中心之间的互通。

    具体配置过程请参考配置文件。

  4. 数据中心A和数据中心B内配置BGP EVPN协议创建部署分布式网关的VXLAN隧道
    1. 在Leaf上配置业务接入点

      # 配置Leaf1。

      [~Leaf1] bridge-domain 10
      [*Leaf1-bd10] quit
      [*Leaf1] interface GigabitEthernet 0/2/0.1 mode l2
      [*Leaf1-GigabitEthernet0/2/0.1] encapsulation dot1q vid 10
      [*Leaf1-GigabitEthernet0/2/0.1] rewrite pop single
      [*Leaf1-GigabitEthernet0/2/0.1] bridge-domain 10
      [*Leaf1-GigabitEthernet0/2/0.1] quit
      [*Leaf1] commit

      Leaf2、Leaf3、Leaf4的配置与Leaf1配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

    2. 在数据中心A的Leaf1和Leaf2之间、数据中心B的Leaf3和Leaf4之间配置IBGP EVPN对等体关系

      # 在Leaf1上配置IBGP EVPN对等体关系

      [~Leaf1] bgp 100
      [*Leaf1-bgp] peer 6.6.6.6 as-number 100
      [*Leaf1-bgp] peer 6.6.6.6 connect-interface LoopBack 1
      [*Leaf1-bgp] l2vpn-family evpn
      [*Leaf1-bgp-af-evpn] peer 6.6.6.6 enable
      [*Leaf1-bgp-af-evpn] peer 6.6.6.6 advertise encap-type vxlan
      [*Leaf1-bgp-af-evpn] quit
      [*Leaf1-bgp] quit
      [*Leaf1] commit

      Leaf2、Leaf3、Leaf4的配置与Leaf1配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

    3. 在Leaf上配置VPN实例和EVPN实例

      # 配置Leaf1。

      [~Leaf1] ip vpn-instance vpn1
      [*Leaf1-vpn-instance-vpn1] vxlan vni 5010
      [*Leaf1-vpn-instance-vpn1] ipv4-family
      [*Leaf1-vpn-instance-vpn1-af-ipv4] route-distinguisher 11:11
      [*Leaf1-vpn-instance-vpn1-af-ipv4] vpn-target 1:1
      [*Leaf1-vpn-instance-vpn1-af-ipv4] vpn-target 11:1 evpn
      [*Leaf1-vpn-instance-vpn1-af-ipv4] quit
      [*Leaf1-vpn-instance-vpn1] quit
      [*Leaf1] evpn vpn-instance evrf1 bd-mode
      [*Leaf1-evpn-instance-evrf1] route-distinguisher 10:1
      [*Leaf1-evpn-instance-evrf1] vpn-target 11:1
      [*Leaf1-evpn-instance-evrf1] quit
      [*Leaf1] bridge-domain 10
      [*Leaf1-bd10] vxlan vni 10 split-horizon-mode
      [*Leaf1-bd10] evpn binding vpn-instance evrf1
      [*Leaf1-bd10] quit
      [*Leaf1] commit

      Leaf2、Leaf3、Leaf4的配置与Leaf1配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

    4. 在Leaf上使能头端复制功能

      # 在配置Leaf1。

      [~Leaf1] interface nve 1
      [*Leaf1-Nve1] source 5.5.5.5
      [*Leaf1-Nve1] vni 10 head-end peer-list protocol bgp
      [*Leaf1-Nve1] quit
      [*Leaf1] commit

      Leaf2、Leaf3、Leaf4上的配置与Leaf1配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

    5. 在Leaf上配置VXLAN三层网关

      # 配置Leaf1。

      [~Leaf1] interface vbdif10
      [*Leaf1-Vbdif10] ip binding vpn-instance vpn1
      [*Leaf1-Vbdif10] ip address 10.1.1.1 24
      [*Leaf1-Vbdif10] arp distribute-gateway enable
      [*Leaf1-Vbdif10] arp collect host enable
      [*Leaf1-Vbdif10] quit
      [*Leaf1] commit

      Leaf2、Leaf3、Leaf4上的配置与Leaf1配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

    6. 数据中心A的Leaf1和Leaf2之间、数据中心B的Leaf3和Leaf4之间、Leaf2和Leaf3之间配置发布IRB类型的路由

      # 配置Leaf1。

      [~Leaf1] bgp 100
      [*Leaf1-bgp] l2vpn-family evpn
      [*Leaf1-bgp-af-evpn] peer 6.6.6.6 advertise irb
      [*Leaf1-bgp-af-evpn] quit
      [*Leaf1-bgp] quit
      [*Leaf1] commit

      # 配置Leaf2。

      [~Leaf2] bgp 100
      [*Leaf2-bgp] l2vpn-family evpn
      [*Leaf2-bgp-af-evpn] peer 5.5.5.5 advertise irb
      [*Leaf2-bgp-af-evpn] peer 7.7.7.7 advertise irb
      [*Leaf2-bgp-af-evpn] quit
      [*Leaf2-bgp] quit
      [*Leaf2] commit

      Leaf4的配置与Leaf1的配置类似，Leaf3的配置与Leaf2的配置类似，这里不再赘述。具体配置过程略，请参考配置文件。

      配置完成后，在Leaf上执行display vxlan tunnel命令，可以看到建立的VXLAN隧道信息。以Leaf1的显示为例：
      [~Leaf1] display vxlan tunnel
      Number of vxlan tunnel : 1
Tunnel ID   Source           Destination      State  Type    Uptime
---------------------------------------------------------------------
4026531841  5.5.5.5          6.6.6.6          up     dynamic 00:05:36

  5. 在Leaf2和Leaf3上配置BGP EVPN协议创建VXLAN隧道
    1. 在Leaf2和Leaf3上配置EBGP EVPN对等体关系

      由于Leaf2和Leaf3上存在VPN实例和EVPN实例，因此在Leaf2和Leaf3上配置仅需要配置EBGP EVPN对等体，保证IP路由可达即可。

      # 配置Leaf2。

      [~Leaf2] bgp 100
      [*Leaf2-bgp] peer 7.7.7.7 as-number 200
      [*Leaf2-bgp] peer 7.7.7.7 connect-interface LoopBack1
      [*Leaf2-bgp] peer 7.7.7.7 ebgp-max-hop 255
      [*Leaf2-bgp] l2vpn-family evpn
      [*Leaf2-bgp-af-evpn] peer 7.7.7.7 enable
      [*Leaf2-bgp-af-evpn] peer 7.7.7.7 advertise encap-type vxlan
      [*Leaf2-bgp-af-evpn] quit
      [*Leaf2-bgp] quit
      [*Leaf2] commit

      # 配置Leaf3。

      [~Leaf3] bgp 200
      [*Leaf3-bgp] peer 6.6.6.6 as-number 100
      [*Leaf3-bgp] peer 6.6.6.6 connect-interface LoopBack1
      [*Leaf3-bgp] peer 6.6.6.6 ebgp-max-hop 255
      [*Leaf3-bgp] l2vpn-family evpn
      [*Leaf3-bgp-af-evpn] peer 6.6.6.6 enable
      [*Leaf3-bgp-af-evpn] peer 6.6.6.6 advertise encap-type vxlan
      [*Leaf3-bgp-af-evpn] quit
      [*Leaf3-bgp] quit
      [*Leaf3] commit

    2. 配置EVPN路由中的IRB路由、IP前缀路由的重生成功能

      # 配置Leaf2。

      [~Leaf2] bgp 100
      [*Leaf2-bgp] l2vpn-family evpn
      [*Leaf2-bgp-af-evpn] peer 5.5.5.5 import reoriginate
      [*Leaf2-bgp-af-evpn] peer 5.5.5.5 advertise route-reoriginated evpn ip
      [*Leaf2-bgp-af-evpn] peer 7.7.7.7 import reoriginate
      [*Leaf2-bgp-af-evpn] peer 7.7.7.7 advertise route-reoriginated evpn ip
      [*Leaf2-bgp-af-evpn] quit
      [*Leaf2-bgp] quit
      [*Leaf2] commit

      # 配置Leaf3。

      [~Leaf3] bgp 200
      [*Leaf3-bgp] l2vpn-family evpn
      [*Leaf3-bgp-af-evpn] peer 8.8.8.8 import reoriginate
      [*Leaf3-bgp-af-evpn] peer 8.8.8.8 advertise route-reoriginated evpn ip
      [*Leaf3-bgp-af-evpn] peer 6.6.6.6 import reoriginate
      [*Leaf3-bgp-af-evpn] peer 6.6.6.6 advertise route-reoriginated evpn ip
      [*Leaf3-bgp-af-evpn] quit
      [*Leaf3-bgp] quit
      [*Leaf3] commit

  6. 验证配置结果

    在Leaf上执行display vxlan tunnel命令，可以看到建立的VXLAN隧道信息。以Leaf2的显示为例：

    [~Leaf2] display vxlan tunnel
    Number of vxlan tunnel : 2
Tunnel ID   Source           Destination      State  Type    Uptime
---------------------------------------------------------------------
4026531841  6.6.6.6          5.5.5.5          up     dynamic 00:11:01
4026531842  6.6.6.6          7.7.7.7          up     dynamic 00:12:11

    在Leaf上执行display ip routing-table vpn-instance vpn1命令可查看IP路由信息。以Leaf1的显示为例：

    [~Leaf1] display ip routing-table vpn-instance vpn1
     Route Flags: R - relay, D - download to fib, T - to vpn-instance, B - black hole route
------------------------------------------------------------------------------
Routing Table : vpn1
         Destinations : 8        Routes : 8

    配置完成后，VMa1和VMb2之间可以互相通信。
