if you ping 172.16.255.255 and all your router have "ip subnet-zero"
configured then all the devices on the "last subnet"( that contains the
broadcast address 172.16.255.255) of 172.16.0.0 will do icmp reply. if "
ip subnet-zero" is not configured then all the devices on 172.16.0.0 will
do icmp reply.
Hope it helps
