IPv6 Router Advertisement (RA) Guard
The IPv6 RA guard provides support to perform conditional forwarding or blocking of the router
advertisement messages that are received at the network device platform. This functionality analyzes and
filters the RAs sent by the devices and compares the configuration information on the layer 2 device with
the RA frame. Once the layer 2 device validates the content of the RA frame against the configuration, it
forwards the RA to its unicast or multicast destination. On failure to validate the RA frame content, the RA
frame is dropped.
The IPv6 RA guard supports two different modes:
• Host mode — When a policy with device role as host is applied on an interface, all the RA packets are
dropped without validation. You can also configure the host mode policy with VLAN option to drop
the RA packets on that specific VLAN and port.
• Router mode — When a policy with device role as router is applied on an interface, all the RA packets
are validated based on the configuration information in the policy. Similarly, you can also apply this
mode over any specific VLAN and the validation is performed only for that particular VLAN RA packets.
To configure the IPv6 RA guard, use the following Dell Networking OS commands.
