What is a limitation when utilizing both IPv4 and IPv6 ACLs on a router?

  • A device can run only IPv4 ACLs or IPv6 ACLs.
  • Both IPv4 and IPv6 ACLs can be configured on a single device, but cannot share the same name.
  • IPv4 ACLs can be numbered or named whereas IPv6 ACLs must be numbered.
  • IPv6 ACLs perform the same functions as standard IPv4 ACLs.

Explanation: IPv4 and IPv6 ACLs can be configured on the same device as long as they utilize different ACL names. IPv6 ACLs provide the same functionality as named IPv4 extended ACLs but cannot have the same name as any IPv4 ACLs.
