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 lters the RAs sent by the devices and compares the
conguration information on the layer 2 device with the RA frame. Once the layer 2 device validates the content of the RA frame
against the conguration, 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 dierent 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 congure the host mode policy with VLAN option to drop the RA packets on that specic VLAN and
port.
