Re: Routes and routing tables

[Robert Bowman <rob () elite exodus net>]

There is a HUGE problem with regards to this.  When I look at "certain" 
providers and the way they are advertising, this is very common:

206.79.0.0/16
206.79.108.0/24
206.79.224.0/22

etc etc.

They are advertising their 16 right, and then are putting more specific 
routes in afterwards.  Doesn't make much sense, however I can see certain
situations why it is happening.. 

In certain circumstances, the people will advertise every class C in a /16 as
well as advertising the /16.  It's turned into something worse than pre-CIDR.


The above addresses are Exodus Communications.  I don't want to turn this 
into a pointing of fingers thread.
