Hi!<BR>
<BR>
I'm doing some test with perfdhcp and I don't understand some things. For example, I'm sending just one broadcast request with the following command:<BR>
<BR>
<TT># perfdhcp -4 -b mac=fb:01:00:00:00:00 -R 1 -r 1 -n 1 -l ens256 -B</TT><BR>

The request is collected with a dhcp relay and send it to the kea dhcp server which replying to the request. Why in a tcpdump in the kea dhcp server I see so many Requests and Replys?, exactly 18:<BR>
