[f-nsp] Route Not Entering Routing Table

ok.. what is it what you are trying do here?
I see two default routes configured.. do you have 2 different uplinks?

It seems you have the uplinks connected to resp. ethe 1/1 
(4.53.232.90/30) and ethe 1/2 (70.42.176.196/30).
Ethe 1/1 is down, Ethe 1/2 is up, that's why ethe 1/1 doesn't appear in 
the 'show ip route static' or 'direct' output.
Since the distances are equal on both default routes they should both 
appear in 'show ip route static' if both links were up.

Anyway.. it seems there's a physical issue here you should solve first..
could you post the output of  'show media'?
And what's connected on the other end of the circuit? Is everything ok 
over there?

Best,
  - Jeroen
