5.1.1 Network Requirements
As shown below, User 1 and User 2 are legal IPv6 users in the LAN and connected to
port 1/0/1 and port 1/0/2. Both of them are in the default VLAN 1. The router has been
configured with security feature to prevent attacks from the WAN. Now the network
administrator wants to configure Switch A to prevent ND attacks from the LAN.

manually bound.
2) Configure ND Detection globally.
