If there is multiple path from source to destination, the loopback interface provides a stable address for protocols (i.e. OSPF, BGP, Telnet) to use so that they can avoid any impact if the physical interface is down. You can configure any IP Address in the loopback interface as long as they are routable but I recommend you use an IP Address depends on their location and security zone (Private or Public). You can also use any subnet mask but I recommend you use /32 subnet mask.
I used a very basic config on a router placed at a client site. They provided the addressing for the interface into their network. Only created a ptp address created to bring up serial interface. I need to rdp to a server on their network.
I just need to route that IP down the interface on my side via static. Spoke to one of the other engineers and we dont need to amend any PIX policies to allow RDP sessions out.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
