IPv6 uRPF and Neighbor Discovery Throttling

IPv6 source address spoofing should be old news – it’s no different from its IPv4 counterpart. Neighbor discovery exhaustion attack is an IPv6-only phenomenon, enabled by huge IPv6 subnet sizes.

During the IPv6 Security webinar Eric Vyncke described Cisco IOS mechanisms you can use to cope with both. Enjoy!
