Vadim,

This is a historical artifact of our running the NSFnet Backbone
Service (and acting as route provider to several peers who trust us to
take care of them).  I agree, however, and it's an operational burden
on ANS as well to run our configs this way.  In the interest of
simplifying configs, Merit reduced the amount of route echo back at
MAE-East a couple months back (thanks to Steve Richardson).

When the NSFnet Backbone Service changes, I expect this standard
configuration to change.
