Hi Rosy

I have read that ACL should be avoid for route filtering as Prefix-list are
more efficent in the way that they are able to filter. For other filter
purposes obviously Prefix list are no good, i.e. port protocol etc..

I am not sure how the efficency is achieved I guess it is the way in which
the memory is used can be simpler with a Prefix-list than an acl. Probably
meaning it can be done in hardware. Perhaps one of the other members of this
group might know why they are more efficent in detail.

Thanks

Paul

list.Insituation where,using a prefix-list would not give any specific
advantage as such(unless specified of course)...is it ok to use Acls ??
