Subject: Local delivery decision for IP broadcasts

Folks,

The draft for the Router Req document - Revision 2.02 dated
1/3/95 states the following:

The packet is passed to the forwarder and delivered locally if:
If the packet's destination address is an IP broadcast address 
(other than a limited broadcast address) that addresses at 
least one of the logical interfaces associated with the physical
interface on which the packet arrived.

What if I have a broadcast packet that addresses a logical interface
associated with some other physical interface?

Could someone explain the rationale behind restricting it the way it is?

Thanks,

-Kanaiya
