/31 subnet. [7:27742]
Hi group, I'm puzzled by the use of /31 subnets... Anybody can explain me the benefits of such a subnet on an interface ? Thanxx. Nicolas.

I use : tftp-server flash:c3640-is-mz.121-5.T9.bin in my "source" router to allow other routers to copy the ios image from this one.

I had several core routers connected with high bandwidth lines (FastEthernet and ATM OC3), and I needed to upgrade them but I only had access to a subsidiary office connected to the main network via an ISDN line. So I just upload the first router of the main network (via ISDN... take a while...), and I configured this router to be a tftp server. Then I uploaded my IOS image in the others backbone routers from the first one. It's just an example, and I'm sure there is many reasons not to use a router as a tftp server (security, cpu consumption, ...) but the feature exists and it's good to know it :) Regards, Nicolas.
