I'm not sure I understand what the option space is. This is like ISIS
TLV137, protocol will populate some trash there and you'll politely
access. It won't allow you to refer to the peer with any name prior to
having the session up. Much like you won't see ISIS neighbours name
when session is establishing, until it has actually loaded and
processed the TLV137.
