●实验验证

公司内部网络内的主机都能成功访问互联网（下图为PC1ping通PC6）。

●实验总结

本次实验路由器R2和R3上需要配置的命令较多，需要理清思路，仔细的配置好。

路由器R2上需要配置接口和环回地址、ospf动态路由、下发路由和数据转发到互联网的默认路由。

路由器R3上需要配置接口和环回地址、ospf动态路由、rip v2动态路由、下发路由和引入路由。

同时本次实验运用到了下发默认路由的新命令，其含义是本路由器发布一条0.0.0.0/0.0.0.0的路由到域内其他路由器。其他路由器学习到这条默认路由后，下一跳就是指向发布这条路由的路由器。

配置在网关出接口路由器上的命令：

ospf 1

default-route-advertise

配置完后ospf区域内其他路由器会多一条默认路由：

配置在ASBR上的命令:

rip 1

default-route originate

在rip区域内的ASBR上配置下发路由后，其他路由器会多一条默认路由：
