[c-nsp] 2MBit leased line and dsl backup

[Florian Taeger]

Hi,

Both lines go to the same isp (me :)

So i might do ospf over this two lines, but I want to avoide it as far as
possible. I don't like to speek a routing protocol to a router owned by a
customer - I don't like to think of what they might do with the ospf 
digest ...

I'll give the "track" option a try :)

Regards

Florian
