We u= se a shell script that do the following : do from 1 to 10Shutdown em/igb interfacesleep 3Bring em/igb interface uptcp= replay -i em0 -l ospf_hello.pcap=C2=A0sleep3end By running this shell on one side we expect 10 ospf hello packets to get ar= rived at the other side, but tcpdump (on the other side) shows 4, sometimes= 8 and etc ... (not all 10 packets are arrived at the other side). We test this scenario with a Cisco router, and all packets are received at = the Cisco side. What causes this packet loss in FreeBSD (maybe in em or igb= drivers)? I know that this scenario may not have any use in the real world, but I'm c= urious, why Cisco don't have such behavior. Thanks in advance. Regards.
