control lists can be used to overcome this shortcoming.(7) The invocation of the list. An access control list can be used on many different interfaces of the same router, and there is no need to define an access control list with different table numbers and identical content for each interface that needs it. If you do not provide any access control lists to the

Access Control List (ACL) is a List of router interface commands used to Control inbound and outbound data packets. ACL applies to all routing protocols, such as IP, IPX, and AppleTalk. The ACL is also defined based on each protocol. If the router interface is configured to support three Protocol IP addresses, AppleTalk, and IPX, you must define three ACLs to con

4. Basic Redis commands-list, basic redis-list1. The list type is implemented using a double linked list. Therefore, if you want to add elements to both ends, the time complexity is O (1 ), the faster the element gets closer to the two ends. However, the cost is that accessing elements through indexes is slow.2. the ma
