cisco packet switching order

Image
This Lab setup i was trying to understand the Routing TCP/IP vol 1 - cisco packet switching order. In this setup if we enable the debug ip packet on the R1 and see whether packet transferred between Host 1 &  Host 2 ? lets ping from Host2 to Host1 mm execpt some broadcast packet nothing in the debugging output why ? R1#debug ip packet IP packet debugging is on R1# *Mar 1 00:15:00.823: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 R1# *Mar 1 00:15:03.835: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 R1# *Mar 1 00:15:06.839: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 R1# *Mar 1 00:15:29.907: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 R1# *Mar 1 00:15:32.911: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 R1# *Mar 1 00:15:35.911: IP: s=0.0.0.0 (FastEthernet0/0), d=255.255.255.255, len 576, rcvd 2 answer is ip packet debugging only show
