RT1串行链路、RT2串行链路、FW1、AC1之间分别运行RIP和RIPng协议，FW1、RT1、RT2的RIP和RIPng发布loopback2地址路由，AC1 RIP发布loopback2地址路由，AC1 RIPng采用route-map匹配prefix-list重发布loopback2地址路由。RT1配置offset值为3的路由策略，实现RT1-S1/0_RT2-S1/1为主链路，RT1-S1/1_RT2-S1/0为备份链路，ipv4的ACL名称为AclRIP，ipv6的ACL名称为AclRIPng。RT1的S1/0与RT2的S1/1之间采用chap双向认证，用户名为对端设备名称，密码为Key-1122
