H3C GRE VPN基本配置实验
实验拓扑

实验需求
根据图示信息进行IP地址配置。
在R1和R3设备上设置默认路由以实现公网间的互通连接。
在R1和R3设备上部署GRE隧道协议,在此过程中允许两端私网之间的数据互通,并将Tunnel端口的IP地址信息参考附图。
在R1与R3设备间设置动态路由协议以实现本地网络之间的通信连接。
实验步骤
按照图示配置 IP 地址
[R1]display ip interface brief
*down: administratively down
(s): spoofing (l): loopback
Interface Physical Protocol IP address/Mask VPN instance Description
GE0/0 up up 100.1.1.1/24 -- --
GE0/1 up up 192.168.1.254/24 -- --
[R2]display ip interface brief
*down: administratively down
(s): spoofing (l): loopback
Interface Physical Protocol IP address/Mask VPN instance Description
GE0/0 up up 100.1.1.2/24 -- --
GE0/1 up up 100.2.2.2/24 -- --
[R3]display ip interface brief
*down: administratively down
(s): spoofing (l): loopback
Interface Physical Protocol IP address/Mask VPN instance Description
GE0/0 up up 100.2.2.3/24 -- --
GE0/1 up up 192.168.2.254/24 -- --

在 R1 和 R3 上配置默认路由使公网区域互通
[R1]ip route-static 0.0.0.0 0 100.1.1.2
[R3]ip route-static 0.0.0.0 0 100.2.2.2

在 R1 和 R3 上配置 GRE VPN,使两端私网能够互相访问
在R1设备上配置隧道接口,并设置其传输模式为GRE;源地址和目的地址分别设置为本端公网IP地址及对端公网IP地址。
[R1]interface Tunnel 0 mode gre //创建Tunnel口,模式为GRE
[R1-Tunnel0]ip address 192.168.3.1 255.255.255.0 //配置Tunnel0口IP地址
[R1-Tunnel0]source 100.1.1.1 //源地址为本端公网地址
[R1-Tunnel0]destination 100.2.2.3 //目的地址为对端公网地址
%Aug 1 09:46:31:195 2024 R1 IFNET/3/PHY_UPDOWN: Physical state on the interface Tunnel0 changed to up.
%Aug 1 09:46:31:195 2024 R1 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Tunnel0 changed to up.

配置在R3上设置隧道接口,并将其连接模式设置为GRE;该接口的源端口与目的端口应分别连接到本地网络的公用地址与远端设备的公用地址
[R3]interface Tunnel 0 mode gre //创建Tunnel口,模式为GRE
[R3-Tunnel0]ip address 192.168.3.3 255.255.255.0 //配置Tunnel0口IP地址
[R3-Tunnel0]source 100.2.2.3 //源地址为本端公网地址
[R3-Tunnel0]destination 100.1.1.1 //目的地址为对端公网地址
%Aug 1 09:54:11:176 2024 R3 IFNET/3/PHY_UPDOWN: Physical state on the interface Tunnel0 changed to up.
%Aug 1 09:54:11:176 2024 R3 IFNET/5/LINK_UPDOWN: Line protocol state on the interface Tunnel0 changed to up.

在 R1 和 R3 上配置OSPF协议来传递两端私网路由
R1 和 R3 使用 RIP 方法来传递私有网络的路由信息。然而,在这种情况下(即当私网报文需通过 VPN 隧道传输时),必须将 Tunnel 接口加入到 RIP 的配置中,并依靠该接口来完成路由的传递。
在 R1 上配置OSPF,宣告业务网段和 Tunnel 口网段
[R1]ospf 1
[R1-ospf-1]area 0.0.0.0
[R1-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255

在 R3 上配置OSPF,宣告业务网段和 Tunnel 口网段
[R3]ospf 1
[R3-ospf-1]area 0.0.0.0
[R3-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255
[R3-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255

实验验证
检查R1与R3之间的OSPF邻居连接状态,并确认其均为FULL状态;随后通过Tunnel0接口进行连接
[R1]display ospf peer
