Storing Last and Bad PDUs<br />

FTOS stores the last notification sent/received, and the last bad PDU received on per peer basis. The last<br />

bad PDU is the one that causes a notification to be issued. These PDUs are shown in the output of the<br />

command show ip bgp neighbor, as shown in Figure 102.<br />
