  ACL can only be used in the outbound direction of an interface

• ○

  The same ACL can be used on multiple interfaces

• ○

  The ACL rules can only be configured in the following sequence: 10, 20, 30…

• ○

  ACLs cannot be used to filter OSPF traffic because OSPF does not use UDP to encapsulate packets

• ○

  ACLs can be used to match with the TCP/UDP port IDs of packets and to designate the port ID range

  A stable OSPF neighbor relationship can be set up between R1 and R2.

• ○

  After the default network type of the interface on R1 is restored to broadcast, a stable OSPF neighbor relationship can be set up between R1 and R2.

• ○

  After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.

• ○

  Compared with R1, R2 is more likely to become the DR because the DR priority of the interface on R2 is lower than that of R1.
