RIPv2 security

[ohassairi]

     Hi experts

i saw that we can secure ripv2 via authentication (simple and MD5)

i undertand that simple is not quite secure because we can see the plain text when capturing RIP packets

however even with MD5 i can see the authentication data (output of MD5) and i think hacker can copy it and paste it in one RIP packet that he will generate !! isn't it ?  so how much MD5 is secure ?
