Re: VIX Looking Glass (was: AS1853 announcing default)

["Paul G. Donner" <pdonner () cisco com>]

Christian,

The terminology I used was incorrect.  What I meant to say was:
"it appears that AS1853 is announcing a default route (to the 
Looking Glass at VIX -> at least)."  I was merely seeking an 
explanation and wandering if this is what was really intended,
not knowing myself exactly what was intended by this announce.

Regards,

-Donner

p.s. Paul - if you want to forward this to NANOG for me...
