多隧道gre
先配置IP pc机给三层网关 然后 路由器0和路由器3做一个隧道 路由器2 和路由器3做一个隧道
路由器0
Router(config)#int tunnel 60创建通道
Router(config-if)#ip address 192.168.60.1 255.255.255.0配置IP
Router(config-if)#tunnel source g0/1通道源起点
Router(config-if)#tunnel destination 192.168.50.2通道结束
Router(config)#ip route 192.168.50.0 255.255.255.0 192.168.20.2静态路由
Router(config)#ip route 192.168.30.0 255.255.255.0 192.168.20.2静态路由
Router(config)#ip route 192.168.70.0 255.255.255.0 192.168.60.2静态路由
Router(config)#ip route 192.168.40.0 255.255.255.0 192.168.70.1静态路由
路由器3
Router(config)#int tunnel 60
Router(config-if)#ip address 192.168.60.2 255.255.255.0
Router(config-if)#tunnel source g0/0
Router(config-if)#tunnel destination 192.168.20.1
Router(config)#ip route 192.168.20.0 255.255.255.0 192.168.50.1
Router(config)#ip route 192.168.10.0 255.255.255.0 192.168.60.1
Router(config)#int tunnel 70
Router(config-if)#ip address 192.168.70.2 255.255.255.0
Router(config-if)#tunnel source g0/0
Router(config-if)#tunnel destination 192.168.30.2
Router(config)#ip route 192.168.30.0 255.255.255.0 192.168.50.1
Router(config)#ip route 192.168.40.0 255.255.255.0 192.168.70.1
路由器2
Router(config)#int tunnel 70
Router(config-if)#ip address 192.168.70.1 255.255.255.0
Router(config-if)#tunnel source g0/0
Router(config-if)#tunnel destination 192.168.50.2
Router(config)#ip route 192.168.20.0 255.255.255.0 192.168.30.1
Router(config)#ip route 192.168.60.0 255.255.255.0 192.168.70.2
Router(config)#ip route 192.168.10.0 255.255.255.0 192.168.60.1
