What would you consider "invalid icmp source"?

I can think about:

- non-valid Internet address, like 172.16.0.0
- internal addresses on the source field of the IP packet received on
outbound interface (interfaces connected to BB on the lab)
- multicast addresses on the source field of the IP packet

Any other?
