Level3 Question

Sat Nov 12 17:46:45 UTC 2005

Per: 

I had hands experience from EGP, BGP-2, BGP-3, BGP-4, and MP-BGP. 

Cost/Money/Operational Pain drive transitions.  

In EGP/BGP-2 it was 12-15 routers. In BGP-3/BGP thousands.  Now? I'll
let you estimate for Internet routers in the planet. 

Of course, I like you would like things to be orderly.

Exactly.

  - When will the Internet deploy X?

  - Just before it's too late.

How many people on this list remember the transition from BGP3 to
BGP4 and CIDR?  This was, uhh, about 12 years ago.  Before that there
was an EGP to BGP transition, but that was less of an issue.

But history will repeat itself.  Not that I see any great evil in that
