hi,

U can also access lists .. check page 314 BGP routing architectures ..sam
halabi..

try this

access-list 101 permit ip 120.0.0.0 0.0.0.255 host 255.255.255.0

this will make sure that the mask is 24 bits long....

access-list 102 permit ip 120.0.0.0 0.0.255.255. host 255.255.0.0

this will check for a mask of 16 bits

can u try this in your lab n also let me know...

thanx

 

If I'm not wrong you can also use extended acl to block most specific
network

access-list 101 permit ip 12.0.0.0 0.0.0.255 255.255.255.0
255.255.255.255

access-list 102 permit ip 12.0.0.0 0.0.255.255 255.255.0.0
255.255.255.255
