In this video, we're going to discuss IP version six access control lists or IPv6 ACLs on the same
way as with IP version four IPV six access control lists allow you to permit or deny traffic in your
network and are a component of a layered security model.
In the real world, you don't necessarily just want to use access control lists for your security.
You want to implement firewalls and other mechanisms such as protocol analyses, such as intrusion prevention
systems or IPS.
But access lists are typically a first line of defense in security implementations.
Now, IPV six access lists share many of the same characteristics of IP version four.
So the knowledge that you've gained when working with IP version four access lists can also be applied
to IPV six access lists.
So they very similar.
But there are differences between the two that you need to be aware of both of them.
As an example, filter on IP addresses of IP packets and upper layer protocols.
So as an example, you can filter on an IP version for address using an IP version for access list.
IPV six access lists can also filter on a source IPV six IP address or IPV six destination address,
but IPV six access lists can also filter on ICMP or TCP IP or UDP.
You could also use IPV six access lists to implement quality of service policies in your network or
to filter writing advertisements.
However, the CCNA course focuses on the use of IPV six to filter IPV six packets arriving or being
received or being transmitted from router interfaces.
