Re: BGP and memory

  • From: Alex P. Rudnev
  • Date: Wed Oct 13 13:49:31 1999

Sorry, I did not want to blame any developer; I only notified that
even text presentation of this tables get less memory then the structures
in the router. Due to Bill (MS really can't work withouth the heaps of the
memory) memory became the cheap gift this days (talking about the memory
for the BGP tables, not the fast switch buffers memory).

-:) Regards, alex.
