Description (partial)

This is a documentation bug.

Request is to update the note under the "Multiple IPv4 Address" section of "configuring IPv4" document:

Presently following note sounds every device in the segment requires secondary IP address assignment which does not serve the purpose of secondary IP address.

"NoteIf any device on a network segment uses a secondary IPv4 address, all other devices on that same network interface must also use a secondary address from the same network or subnet. The inconsistent use of secondary addresses on a network segment can quickly cause routing loops."
