IP unnumbered is a technique used to conserve IP address space. I believe it
is discussed in RFC 1812 in terms of a possible mechanism that would permit
IP unnumbered. I.e. router RID's can serve as a means of identifying the
devices on either end of serial links and point-to-point subinterfaces of
frame links.
Seeing as OSPF and EIGRP and RIPv2 all work properly over unnumbered links,
I would venture a guess that it makes no difference to the routing protocol.
the links themselves will not appear in any routing tables, whereas if they
were numbered they would.

Subject: question on ipunumbered [7:13846]
Why when using unnumbered interfaces, any routing protocol running across
the serial line must not advertise subnet information ?
Thanks in advance
