IPv6 Neighbor Discovery Router Alert Guard

Managing IPv6 ND RA Guard

This feature prevents malicious and unwitting IPv6 Neighbor Discovery Router Advertisement packets

from entering the network at the edge, so that only specific devices, connected usually to uplink ports

can assign IPv6 addresses to other network devices.

This feature can be enabled on a per-port basis. By attaching the host policy to a port, the IPv6 ND RA

packets received on that port will be dropped at ingress. By attaching the router policy, the IPv6 ND RA

packets will be allowed on that port.

By default, the “router” policy is attached to all ports.

1. Type the config terminal command into the terminal. Press the Enter key.

2. Type the int gigabitethernet 0/1 command into the terminal to select the interface to be

configured. Press the Enter key.

3. Type the ipv6 nd raguard attach-policy host command into the terminal to attach the “host” policy

to the selected port. Press the Enter key.
