We request that your routers be configurable, both globally and and the interface level, with the interface configuration overiding the global configuration, to prevent the forwarding of an IP packet with a source network address different from the network address of the interface on which it was received. We also request that the default configurations of your routers be modified to prevent, globally, said forwarding.I'd be concerned that having this as a default is not necessarily the right thing in sufficiently large numbers of situations as to make this a bad idea.
I know we've collectively been here before, but is it not a reasonable assumption that people whose routing patterns might be assymetrical enough to break this as a default should be expected to be bright enough to switch it off?
