您好，请知：

以下是GRE的配置案例和手册连接，请参考：

02-GRE配置-新华三集团-H3C

1.8  GRE典型配置举例

1.8.1  GRE over IPv4隧道配置举例

1. 组网需求

Router A和Router B分别连接IPv4私有网络Group 1和Group 2。这两个私有网络都使用私网地址，且属于同一个VPN。通过在Router A和Router B之间建立GRE隧道，实现两个私有网络的互联。

2. 组网图

3. 配置准备

在开始下面的配置之前，假设设备各接口的地址都已配置完毕，并且Router A和Router B之间路由可达。

4. 配置步骤

(1)     配置Router A

# 创建Tunnel0接口，并指定隧道模式为GRE over IPv4隧道。

<RouterA> system-view

[RouterA] interface tunnel 0 mode gre

# 配置Tunnel0接口的IP地址。

[RouterA-Tunnel0] ip address 10.1.2.1 255.255.255.0

# 配置Tunnel0接口的源端地址（Router A的GigabitEthernet0/0/2的IP地址）。

[RouterA-Tunnel0] source 1.1.1.1

# 配置Tunnel0接口的目的端地址（Router B的GigabitEthernet0/0/2的IP地址）。

[RouterA-Tunnel0] destination 2.2.2.2

[RouterA-Tunnel0] quit

# 配置从Router A经过Tunnel0接口到Group 2的静态路由。

[RouterA] ip route-static 10.1.3.0 255.255.255.0 tunnel 0

(2)     配置Router B

# 创建Tunnel0接口，并指定隧道模式为GRE over IPv4隧道。

<RouterB> system-view

[RouterB] interface tunnel 0 mode gre

# 配置Tunnel0接口的IP地址。

[RouterB-Tunnel0] ip address 10.1.2.2 255.255.255.0

# 配置Tunnel0接口的源端地址（Router B的GigabitEthernet0/0/2的IP地址）。

[RouterB-Tunnel0] source 2.2.2.2

# 配置Tunnel0接口的目的端地址（Router A的GigabitEthernet0/0/2的IP地址）。

[RouterB-Tunnel0] destination 1.1.1.1

[RouterB-Tunnel0] quit

# 配置从Router B经过Tunnel0接口到Group 1的静态路由。

[RouterB] ip route-static 10.1.1.0 255.255.255.0 tunnel 0

5. 验证配置

# 查看Router A的Tunnel接口状态。

[RouterA] display interface tunnel 0

# 从Router B可以Ping通Router A上GigabitEthernet0/0/1接口的地址。

[RouterB] ping -a 10.1.3.1 10.1.1.1
