RIPv2认证配置

配置步骤：

1、定义密钥链名称   

      key chain 密钥链名称

2、在密钥链上定义密钥(可以定义多个密钥)

      key 1 

      key-string 密码

3、在指定接口上应用密钥链

      int f0/0

      ip rip authentication key-chain 密钥链名称

      ip rip authentication mode md5

4、在指定接口上使用的认证类型是明文还是MD5

       int f0/0

       ip rip authentication mode md5

排错命令：

debug ip rip

show ip rip datebase

R1#show ip rip database
