Repeat http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/146539

There is an active network with users 10.10.10.0/24 (fxp0)

---
#!/bin/sh
arp -ad > /dev/null
I=1
while [ $I -le 253 ] 
do 
    I=$(expr $I + 1)
    arp -S 10.10.10.${I} 00:00:00:00:00:00 pub > /dev/null
done
#
arp -an|egrep -v "10.10.10.1|published"
exit 0
---

execute script 1-40 times
Sometimes the output string:
? (10.10.10.44) at 00:00:00:00:00:00 on fxp0 permanent [ethernet]
? (10.10.10.101) at 00:00:00:00:00:00 on fxp0 permanent [ethernet]
? (10.10.10.132) at 00:00:00:00:00:00 on fxp0 permanent [ethernet]

not prescribed published
must:
? (10.10.10.44) at 00:00:00:00:00:00 on fxp0 permanent published [ethernet]
? (10.10.10.101) at 00:00:00:00:00:00 on fxp0 permanent published [ethernet]
? (10.10.10.132) at 00:00:00:00:00:00 on fxp0 permanent published [ethernet]

ip can be any
00:00:00:00:00:00 taken as an example

same thing when using 'arp -da; arp -f file'


repeat.
