Hello all! I am trying to work out a restoral configuration for some x25 xot calls from stub routers. What I really need is a second loopback interface so that an operator could shut it down manually in order to make a stub router's x25 xot route roll over to the next ip address configured in the route. Is there a method for spoofing up an unused interface so that it also becomes a virtual interface that could easily be shut/noshut?
