三、再创建GRE VPN和MGRE VPN
MGRE VPN:10.1.2.0/24
GRE VPN:10.1.1.0/24
(1)R1、R2、R3构建一个MGRE环境,R1为中心站点。
隧道接口配置:
R1:
[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
[R1-Tunnel0/0/0]source 15.1.1.1
# 配置NHRP(下一跳解析协议)
[R1-Tunnel0/0/0]nhrp network-id 100
[R1-Tunnel0/0/0]q
[R1]dis nhrp peer all
R2:
[R2]int Tunnel 0/0/0
[R2-Tunnel0/0/0]ip add 10.1.2.2 24
[R2-Tunnel0/0/0]tunnel-protocol gre p2mp
[R2-Tunnel0/0/0]source Serial 4/0/0
# 设置与NHRP服务器(Next Hop Resolution Protocol)的条目
[R2-Tunnel0/0/0]nhrp network-id 100
[R2-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register
[R2-Tunnel0/0/0]q
[R2]dis nhrp peer all
R3:
[R3]int Tunnel 0/0/0
[R3-Tunnel0/0/0]ip add 10.1.2.3 24
[R3-Tunnel0/0/0]tunnel-protocol gre p2mp
[R3-Tunnel0/0/0]source Serial 4/0/0.
[R3-Tunnel0/0/0]nhrp network-id 100
[R3-Tunnel0/0/0]nhrp entry 10.1.2.1 15.1.1.1 register
[R3-Tunnel0/0/0]q
[R3]dis nhrp peer all
(2)R1、R4间为点到点的GRE。
R1:
[R1]int Tunnel 0/0/1
[R1-Tunnel0/0/1]ip add 10.1.1.1 24
[R1-Tunnel0/0/1]tunnel-protocol gre
[R1-Tunnel0/0/1]source 15.1.1.1
[R1-Tunnel0/0/1]destination 45.1.1.4
R4:
[R4]int Tunnel 0/0/1
[R4-Tunnel0/0/1]ip add 10.1.1.4 24
[R4-Tunnel0/0/1]tunnel-protocol gre
[R4-Tunnel0/0/1]source 45.1.1.4
[R4-Tunnel0/0/1]destination 15.1.1.1
(3)在R1到R5上配置路由协议(RIP)传递两端私网路由
R1:
[R1]rip 1
[R1-rip-1]version 2
[R1-rip-1]network 192.168.1.0
[R1-rip-1]network 10.0.0.0
[R1-rip-1]undo summary
[R1-rip-1]q
查看路由表中的rip信息
[R1]dis ip routing-table protocol rip
[R1]int Serial 4/0/0
关闭RIP水平分割:
[R1-Serial4/0/0]undo rip split-horizon
[R1]int tunnel 0/0/0
开启伪广播 :
[R1-Tunnel0/0/0]nhrp entry multicast dynamic
R2:
[R2]rip 1
[R2-rip-1]v 2
[R2-rip-1]undo summary
[R2-rip-1]network 192.168.2.0
[R2-rip-1]network 10.0.0.0
[R2-rip-1]q
[R2]dis ip routing-table protocol rip
[R2]int t0/0/0
[R2-Tunnel0/0/0]undo rip split-horizon
[R2-Tunnel0/0/0]q
[R2]
R3:
[R3]rip 1
[R3-rip-1]v 2
[R3-rip-1]undo summary
[R3-rip-1]network 192.168.3.0
[R3-rip-1]network 10.0.0.0
[R3-rip-1]q
[R3]dis ip routing-table protocol rip
[R3]int t0/0/0
[R3-Tunnel0/0/0]undo rip sp
[R3-Tunnel0/0/0]undo rip split-horizon
[R3-Tunnel0/0/0]q
[R3]
R4:
[R4]rip 1
[R4-rip-1]v 2
[R4-rip-1]undo summary
[R4-rip-1]network 192.168.4.0
[R4-rip-1]network 10.0.0.0
[R4-rip-1]q
[R4]
测试一下私网与公网是否已经是可通:
示例:
PC1 ping PC3:
PC>ping 192.168.2.3
Ping 192.168.2.3: 32 data bytes, Press Ctrl_C to break
20.00% packet loss
PC1 ping PC6:
PC>ping 192.168.3.6
Ping 192.168.3.6: 32 data bytes, Press Ctrl_C to break
0.00% packet loss
测试通过!!!
四、配置NAT协议(easy IP)使得所有的PC可以访问R5环回
R1:
<R1>sys
[R1]acl 2000
[R1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[R1-acl-basic-2000]q
[R1]int Serial 4/0/0
[R1-Serial4/0/0]nat outbound 2000
[R1-Serial4/0/0]q
[R1]
R2:
[R2]acl 2000
[R2-acl-basic-2000]rule permit source 192.168.2.0 0.0.0.255
[R2-acl-basic-2000]q
[R2]int Serial 4/0/0
[R2-Serial4/0/0]nat outbound 2000
[R2-Serial4/0/0]q
[R2]
R3:
<R3>sys
[R3]acl 2000
[R3-acl-basic-2000]rule permit source 192.168.3.0 0.0.0.255
[R3-acl-basic-2000]q
[R3]int Serial 4/0/0
[R3-Serial4/0/0]nat outbound 2000
[R3-Serial4/0/0]q
[R3]
R4:
<R4>sys
[R4]acl 2000
[R4-acl-basic-2000]rule permit source 192.168.4.0 0.0.0.255
[R4-acl-basic-2000]q
[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]nat outbound 2000
[R4-GigabitEthernet0/0/0]q
[R4]
测试一下:
示例:
PC1 ping R5的环回路由:
PC>ping 5.5.5.5
0.00% packet loss
PC7 ping R5 的环回路由:
PC>ping 5.5.5.5
Ping 5.5.5.5: 32 data bytes, Press Ctrl_C to break
20.00% packet loss
测试通过!!!
