                           That little routing issue
                                        
I also did manage to find a work-around for the little OSPF (Open Shortest
Path First) problem [1] I've been having. What's happening is that on the
customer's router, when the T-1 link is up, the routes, including the all
important default route, are populated through OSPF. If the T-1 goes down,
then all the OSPF generated routes disappear, including the all important
default route. 

Upshot—if the T-1 goes down, the customer can't see the Internet. 

But oddly enough, when the T-1 goes down, OSPF still shows a neighbor
connection through the DSL (Digital Subscriber Line) link. But it won't
populate the routes. 

The work-around? A static default route through the DSL connection but
weighted so heavily that the default route through OSPF (in which case goes
through the T-1) is preferred if it exists. 

So now, the T-1 goes down, the OSPF routes disappear, leaving the static
default route over the DSL so the customer can still see the Internet. 

It works, but I don't like it.
