[c-nsp] A simple access list question

[r.sahney]

Hi All,
     I have failed to find a written detail regarding the difference
in impact of the access-list below , assuming i have networks
192.168.131.0 ,132.0 , 133.0 etc.

-- What impact these lists will make in actual production if written incorretly.

right way is --- 
permit ip 192.168.131.0 0.0.0.0255 192.168.200.0 0.0.0.255 any

wrong would be --
permit ip 192.168.0.0 0.0.255.255  192.168.200.0 0.0.0.255 any

In eigrp advertisement i m advertising 
network 192.168.131.0 
network 192.168.132.0 etc

Any written document stating its impact ? or any suggestions will be
appreciated.

regards
raj
