        Guys
        
        If u are asked to allow say 3 routes (140.1.0.0,
        141.2.0.0 & 142.3.0.0) in to your rack from a
        backbone. What type of wildcard would you use in ur
        ACL. Would the following be the best?
        
        access-list 1 permit 140.1.0.0 0.0.0.0
        access-list 1 permit 141.2.0.0 0.0.0.0
        access-list 1 permit 142.3.0.0 0.0.0.0
        
        OR:
        
        access-list 1 permit 140.1.0.0 0.0.255.255
        access-list 1 permit 141.2.0.0 0.0.255.255
        access-list 1 permit 142.3.0.0 0.0.255.255
        
        ?
        
        Thanks
