This uniquely identifies the router over the entire internet. An IP address is not required on point-to-point networks. Such a point-to-point network is called "unnumbered". In unnumbered links, each endpoint of a point-to-point link is anonymous and takes its IP address from the router id itself (if a router has 3 ppp links, each will have the same "IP address" - they will be singled out by the IP address of the other endpoint). This allows to save IP addresses and to not use private IP addresses on a backbone network. So back to the initial question : can the IP stack of FreeBSD support such links ? (I don't know what could be the result of an ifconfig request on such links, for example) Hoping my question is a bit clearer this time TfH > > Hello, > > > > I've just looked at the man page for 2.2.7-R PPP and I don't find any > > mention of unnumbered links (which allows not to assign an IP address to > > each extremity of a PPP link). > > > > Q : will there be any support for PPP unnumbered links in FreeBSD ?
