Un-numbered point to point. doubt

[kamatchi soundaram <kamatchi at TDD.SJ.NEC.COM>]

Hello all!,

  I presently working on OSPF un-numbered point to point support. I need
some clarification in implementing this support..

Well! to support this un-numbered point to point, the IP need to support
this feature. If some body put some light on this it will be great! Yes!
even if get some general view about how the IP need to support the
un-numbered point to point of OSPF??

 Is there any standard available for this??

Well! what i know is:
* in case of un-numbered point to point, the one of valid IP address of
other interface will be assigned to this un-numbered p2p. So, that whenever
OSPF sends the packet, it will use this IP address as source address in the
IP header. But how exactly it is implemeted?? Especially in linux kind of
IP. (and stack).

Thanks,
GKS.
