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
