Having router security features are important,
but when they don't go well, and that basically
means that either they're not doing what they're expected
to do, or they're killing too much traffic,
why did my routing protocol die?
Why isn't this traffic being allowed?
If it's not working correctly, we need to troubleshoot that.
So in this set of videos, and I'll also include some labs
as well, we're going to take a look
at filtering the ACLs for IPv4, including standard access
list, extended access list, and time-based access list.
If you're thinking, well, what about IPv6,
we're going to cover that too.
Take a look at filtering access controllers for IPv6 as well. WEBVTT X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

I'd also like to talk with you about a concept called URPF,
Unicast Reverse Path Forwarding, which
is going to help the router drop packets if it doesn't agree
on where that source address is showing up those packets, where
the source address is showing up on its interfaces.
So that's what we have to look forward to in the set of videos
and I'll see you in the very next video.
