I have a pc in my LAN generating lots of packet to the broadcast IP address of my network as well as the 255.255.255.255 IP .
I used netflow in the router and from the show ip route cache flow command
I can see that the traffic has destination interface Null and sends around 20k packets .
Source interface gig0/0 Ip 192.168.1.33 Destination interface **Null** **Destination ip 192.168.1.255** **Destination ip 255.255.255.255** **Pro 11**
This behavior has caused my cpu to reach 80-90% .
Can I have some help if t this is something relative to the user or misconfig to the router interface ?
