• 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.
