>Release:        FreeBSD 2.1 STABLE i386
>Environment:

	2.1 STABLE, 486dx2-66, 2 ed interfaces

>Description:

	on 1.1.5.1, when doing an
		ifconfig ed0 140.174.2.174 netmask 255.255.255.0 alias
	it works.
	on 2.1 STABLE, it is broken in 2 ways: ifconfig complains, and it
		does not work, even though netstat likes it.
	note that sometimes I have seen it work for interfaces other than
	the first one, and even for the first one, for a very short time.

>How-To-Repeat:

	ifconfig ed0 140.174.2.174 netmask 255.255.255.0 alias
	ping 140.174.2.174

	
>Fix:
	
	no idea. rip out the multicast stuff and roll back to 1.1.5.1? nah.
