subnet routes

  • From: Andrew Partan
  • Date: Mon Feb 12 22:14:35 1996

I happened to check to see how many subnet routes there are out there
(subnets of classical A/B/C nets being injected into the global BGP
tables).  There are a lot of them...

Of these, there are 47 that are longer than a /24.
       2      /25
      23      /26
       4      /27
       4      /28
       2      /29
      12      /30
