Re: /8s and filtering
Here is one reason for some to care :
If you want to do interdomain multicast, and your
address space is not announced globally (say because you have a /24 that is
not from the swamp), you are likely to be black-holed
due to RPF failures (as your unicast and multicast routing is likely to be different).
This has caused problems from time to time...
