RIPv2認證配置

配置步驟：

1、定義密鑰鍊名稱   

      key chain 密鑰鍊名稱

2、在密鑰鍊上定義密鑰(可以定義多個密鑰)

      key 1 

      key-string 密碼

3、在指定接口上應用密鑰鍊

      int f0/0

      ip rip authentication key-chain 密鑰鍊名稱

      ip rip authentication mode md5

4、在指定接口上使用的認證類型是明文還是MD5

      ip rip authentication mode md5

排錯指令：

debug ip rip

show ip rip datebase

R1#show ip rip database
