OK Let me have a go at this - A router by definition has at least two interfaces, in most cases it has many more.
How do we define the ip address of the router? Is it an Ethernet (LAN facing) interface or a (for example) Serial, HSSI or other WAN facing interface? If any of these interfaces goes down (fails) then we cannot get to the router. This is why we set a loopback interface address - nothing to do with routing or metrics etc, just making sure that we can reach the router Best regards, Dom Stocqueler SysDom Technologies Visit our website - www.sysdom.org -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of MADMAN Sent: 05 August 2003 19:47 To: [EMAIL PROTECTED] Subject: Re: Loopback Interface [7:73305] I think your thinking way too hard about this;) A loobback is nothing more than a logical interface as opposed to a physical interface. As far as the routing process is concerned it's just another interface. Don't know how to articulate it any further.
