Use of loopback.

Hi all,

just one question regarding the use of loopback interface.

I noticed some one in the newsgroup reported configurations with the following statements

interface Loopback0 ip address ip nat outside ip virtual-reassembly ..........

ip unnumbered Loopback0

So I would ask you if I can use loopback to standardize my configurations of about 20-30 837 routers which differ only by the kind of ADSL technology used but are basically the sames regarding tunnels, ip routes, route-maps and so on. Can names be assigned to network and not to only to host to increase standardization on config file? I think those features will make my configurations error-proof on first installations of the routers.
