access-list 101 permit ip host 6.6.6.0 host 255.255.255.0




OK I know what it does by why is it written like this ??

this read like " any traffic from the network address to the subnet address"

Why not just have it as a standard access list that covers the whole subnet ??

Does any one have any more info on this format of ACL's ?

    Its just a data field that is passed to the process, just the human readable part makes it confusing.

    I much prefer a prefix list to ACL anytime dealing with BGP anyway.

    So lazy coders making it easy for them selves :) using the existing ACL syntax to pass the arguments to the process.

    It's written like that, because there is a difference between "this subnet" and "any subnet or host that falls within this mask"
