Brian, Moreover, you suggestion will apply only if i am proxy arping B
from A and vice versa.. But when i arp any other subnets, both routers
will have these routers..
In any case, i think bill's understanding with this issue is correct.
Routers seem to responding only to the connect hosts. (They verify
source addresses before responding with MAC). However, in our case,
our legacy hosts, which uses same NIC for both subnets, never uses
second subnet to ask for MAC. So always R1 responds..
