Object
If this object is set to 'true', the router ignores any MGMD packets that do not have the Router Alert option set. Ignoring these packets provides improved security, because it is desirable for routers not to forward forged MGMD packets (legitimate packets have a TTL/Hop Limit of 1), and this is easier to achieve if legitimate packets have the Router Alert option set. However, ignoring these packets breaks backwards compatibility with IGMPv1 implementations, and with early implementations of IGMPv2. For MLD, this object is read-only and is always set to 'true'.
