Why are inbound ACLs more efficient for the router than outbound ACLs?

  • Inbound ACLs deny packets before routing lookups are required.
  • Inbound ACL operation requires less network bandwidth than outbound.
  • Inbound ACLs permit or deny packets to LANs, which are typically more efficient than WANs.
  • Inbound ACLs are applied to Ethernet interfaces, while outbound ACLs are applied to slower serial interfaces.
