1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 51.869/51.869/51.869/nan ms四.RIP动态路由配置：/techpubs/en_US/junos13.3/topics/topic-map/rip-authentication.html--junos如果不配置认证，不用配置策略，配置认证，如果不配置策略，接口发出的rip包不会带有认证信息，junos只能接收rip。A.JUNOS:①配置策略：set policy-options policy-statement advertis-routers-through-rip term 1 from protocol direct
set policy-options policy-statement advertis-routers-through-rip term 1 from protocol rip
set policy-options policy-statement advertis-routers-through-rip term 1 then accept②配置接口，将接口加入groupset protocols rip group rip-group neighbor em1.0③group export策略set protocols rip group rip-group export advertis-routers-through-rip④配置认证全局：set protocols rip authentication-type md5
set protocols rip authentication-key cisco接口：set protocols rip group rip-group neighbor em1.0 authentication-type md5
set protocols rip group rip-group neighbor em1.0 authentication-key ciscoB.R2：①基本配置：router rip

network 192.168.1.0②配置认证：key chain rip
