access lists

[carl_townshend]

Hi all, I know we have access list numbers, my question is what are these used for, as we can have mutliple entries for each access list group number ,ie

access list 1 permit ip any any

access list 1 permy ip any host x.x.x.x

thanks

Carl

Hi Carl,

The ACL number (which is "1" in your case) is used to attach the ACL either to an interface or route-filtering or whatever (look to it as an ID for the ACL), the multiple entries are processed in sequence Top to bottom, with an implicit deny at the end.

HTH,
