H3C VSR2000 或者msr36-20配置Vxlan

开启L2×××能力

[SH6800]l2*** enable 

创建VSI实例***a和Vxlan10011

[SH6800]vsi ***a 
[SH6800-vsi-***a]vxlan 10011 
[SH6800-vsi-***a-vxlan-10011]qui
[SH6800-vsi-***a]quit

配置接口loopback0 地址，作为隧道的源端地址

[SH6800]interface LoopBack 0 
[SH6800-LoopBack0]ip add 2.2.2.7 255.255.255.255
[SH6800-LoopBack0]quit

在SH6800和N9K-1之间建立Vxlan隧道

• 创建模式为Vxlan的隧道接口Tunnel1
• 指定隧道的源端地址为本地接口loopback0的地址
• 指定隧道目的端地址N9K-1的loopback0地址

[SH6800]interface Tunnel 1 mode vxlan 
[SH6800-Tunnel1]source 2.2.2.7 
[SH6800-Tunnel1]destination 2.2.2.1 
[SH6800-Tunnel1]quit

配置Tunnel1与Vxlan10011关联

[SH6800]vsi ***a
[SH6800-vsi-***a]vxlan 10011
[SH6800-vsi-***a-vxlan-10011]tunnel 1
[SH6800-vsi-***a-vxlan-10011]quit
[SH6800-vsi-***a]quit

在接入服务器接口上与VSI实例***a关联。

#当只有一个vlan通过的时候可以用这个方法。这里只有vlan11。
[SH6800]interface GigabitEthernet 1/0
[SH6800-GigabitEthernet1/0]port link-mode route 
[SH6800-GigabitEthernet1/0]xconnect vsi ***a 
[SH6800-GigabitEthernet1/0]quit

#当有多个vlan通过Vxlan通信，就需要匹配vlan
[SH6800]interface GigabitEthernet 1/0
[SH6800-GigabitEthernet1/0]port link-mode route 
[SH6800-GigabitEthernet1/0]quit

[SH6800]interface GigabitEthernet 1/0.1 
#vid之后跟的是匹配的vlan
[SH6800-GigabitEthernet1/0.1]vlan-type dot1q vid 11 
#vsi之后跟的是相应的vsi实例
[SH6800-GigabitEthernet1/0.1]xconnect vsi ***a
[SH6800-GigabitEthernet1/0.1]quit

#例如还有一个vlan12 
[SH6800]interface GigabitEthernet 1/0.2
[SH6800-GigabitEthernet1/0.2]vlan-type dot1q vid 12
[SH6800-GigabitEthernet1/0.2]xconnect vsi ***a12
[SH6800-GigabitEthernet1/0.2]quit

#以下是6800的接口与VSI实例关联方法
# 在接入服务器的接口HundredGigE1/0/1上创建以太网服务实例1000，该实例用来匹配VLAN 2的数据帧。
[SwitchC] interface hundredgige 1/0/1
[SwitchC-HundredGigE1/0/1] service-instance 1000
[SwitchC-HundredGigE1/0/1-srv1000] encapsulation s-vid 2
# 配置以太网服务实例1000与VSI实例***a关联。
[SwitchC-HundredGigE1/0/1-srv1000] xconnect vsi ***a
[SwitchC-HundredGigE1/0/1-srv1000] quit
[SwitchC-HundredGigE1/0/1] quit
