6.R1,R2,R3,构成一个MGRE环境,R1为站点中心;
MGRE VPN:10.1.2.0/24
创建隧道Tunnel 0/0/0,并加入到同一个nhrp中,配置如下:
[R1]int Tunnel 0/0/0
[R1-Tunnel0/0/0]ip add 10.1.2.1 24
[R1-Tunnel0/0/0]tunnel-protocol gre p2mp

Mar 30 2024 15:16:13-08:00 R3 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP
on the interface Tunnel0/0/0 has entered the UP state.
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]
7.R1,R4之间为点到点GRE
GRE VPN:10.1.1.0/24
[R1]int Tunnel 0/0/1
[R1-Tunnel0/0/1]ip add 10.1.1.1 24

其他的 向中心站点 开启注册:
[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register
[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register
关闭mgre水平分割机制
[R1-Tunnel0/0/0]undo rip split-horizon
[R2-Tunnel0/0/0]undo rip split-horizon
[R3-Tunnel0/0/0]undo rip split-horizon
9.所有PC设置私有IP为源IP,可以访问R5环回,达到全网通
