Source checking for forwarding filter tables

On MX Series 3D Universal Edge Routers, you can apply a forwarding table filter by using the soure-checking statement at the [edit forwarding-options family inet6] hierarchy level. This discards IPv6 packets when the source address type is unspecified, loopback, multicast or link-local. RFC 4291, IP Version 6 Addressing Architecture, refers to four address types that require special treatment when they are used as source addresses. The four address types are: Unspecified, Loopack, Multicast, and Link-Local Unicast. The loopback and multicast addresses must never be used as a source address in IPv6 packets. The unspecified and link-local addresses can be used as source addresses but routers must never forward packets that have these addresses as source addresses. Typically, packets that contain unspecified or link-local addresses as source addresses are delivered to the local host. If the destination is not the local host, then the packet must not be forwarded. Configuring this statement filters or discards IPv6 packets of these four address types. Configuring this statement filters or discards IPv6 packets of these four address types.
