just wanted to know one thing........what is the rule abt standard and extended access-list....like it should be placed near to source or destination......just confuse abt that an dwhy is that.....thanks in advance....cheers
Cisco classes used to teach that it was best practice to place standard access lists as close to the destination as possible and best to place extended access lists as close to the source as possible. I believe that this is what the original post was asking.
The reasoning for this was that with standard access lists limited ability to discriminate (they only look at source address, and can not look at destination, or protocol type, or port) you could control the impact of the access list by placing it close to the destination. With extended access lists with their greater ability to discriminate traffic (examining both source and destination, and protocol, and port numbers) it was more efficient to place it close to the source.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
