Router security troubleshooting

“

- In this lesson, we're going to take a look at several important router security principles, including IP version 4 ACLs and IP version 6 traffic filters. We'll look at troubleshooting both unicast reverse-path-forwarding and control plane policing configurations. We also want to look at some First-Hop Security features specifically for IP version 6, including IPv6 RA Guard, DHCP V6 Guard, the IPv6 Neighbor Discovery Inspection feature, and using IPv6 Source Guard to verify the source of IP version 6 traffic.
