Re: Doubts in IP Unnumbered!!!

Ok..

          Now tell us in detail what kind of information you want from us.
The behaviour of IP Unnumbered is different for different protocols.

Definiton of IP Unumbered: It is borrowing of IP from other interface of
same router.

Working of IP Unnumbered with different protocols:

RIPv2 : If u use IP Unnumbered on two routers runnning RIP and borrowed IPs
are not in same subnet you need to do switch off the sanity check. By
default Source should be in same subnet for RIP to work.

OSPF : When you use IP Unnumbered on two router running OSPF and borrowed
IPs are not in the same subnet, Still the OSPF adjaceny comes up. This is
due to the fact When OSPF sees the interface as IP unnumbered it will not
send Subnet Mask information in Hellos and hence the adjaceny is up.

In case of frame relay you need to use PPPoFR if the ip address borrowed are
not from the same subnet Or you use a ip to DLCI mapping.

I hope this clears your doubt. Also correct me if i am wrong.
