commit
B.测试：
root> ping 1.1.1.1
PING 1.1.1.1 (1.1.1.1): 56 data bytes
64 bytes from 1.1.1.1: icmp_seq=0 ttl=255 time=51.869 ms

1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 51.869/51.869/51.869/nan ms
PING 1.1.1.1 (1.1.1.1): 56 data bytes
64 bytes from 1.1.1.1: icmp_seq=0 ttl=255 time=51.869 ms

round-trip min/avg/max/stddev = 51.869/51.869/51.869/nan ms
四.RIP动态路由配置：
--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 accept
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 accept
②配置接口，将接口加入group
set protocols rip group rip-group neighbor em1.0
③group export策略
set protocols rip group rip-group export advertis-routers-through-rip
④配置认证
全局：
set protocols rip authentication-type md5
set protocols rip authentication-key cisco
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 cisco
set protocols rip group rip-group neighbor em1.0 authentication-key cisco
B.R2：
①基本配置：
router rip
version 2
network 10.0.0.0
network 192.168.1.0
version 2
network 10.0.0.0
network 192.168.1.0
②配置认证：
key chain rip
key 1
key-string cisco
interface Ethernet0/0
ip rip authentication mode md5
ip rip authentication key-chain rip
key 1
key-string cisco
interface Ethernet0/0
ip rip authentication mode md5
ip rip authentication key-chain rip
备注：测试时发现用c2691-adventerprisek9-mz.124-15.T14.BIN的2691的路由器配置完rip认证后，rip包中不会有认证信息，可能是IOS的问题。
