What does it mean? They won't forward any packets with the source route
option, or just those whose loose-source-route option explicitely mentions the
router in question?

The former would be bad. But I can go with the later, because this
router would be under my control.

I also believe that in IPv6 world you cannot just disable the Source
Routing feature (called Routing Header ) because it is necessary
for mobility (don't remember the details, but will look at it).
