>Description:
I have a following configuration:

  ifconfig ed0 192.168.1.1/24
  ifconfig ed0 192.168.10.1/24 alias

After 5 minutes, the first IP (192.168.1.1) become unreachable if I do a ping to it.
I could see that route to 192.168.1.0/24 was deleted. But, 192.168.10.0/24 is working well.

Can anybody help me ?

>How-To-Repeat:
Intall the FreeBSD 7-RELEASE
Configure the interface:
  ifconfig ed0 192.168.1.1/24
  ifconfig ed0 192.168.10.1/24 alias
Ping the first IP:
  ping 192.168.1.1
Wait for six minutes and you will see the problem.
After five minutes, the problem will solve and it will appear five minutes after.

>Fix:
No fix until now.
