In-Reply-To: <4B8FEB0F.5060107@blastro.com> Date: Thu, 4 Mar 2010 12:23:56 -0500 From: Jack Carrozzo <jack@crepinc.com> To: Alex Thurlow <alex@blastro.com> Cc: nanog@nanog.org Errors-To: nanog-bounces+nanog.discuss=bloom-picayune.mit.edu@nanog.org If you want to keep it cheap, roll out another Quagga edge - one to each peer. Drop default into OSPF from both edges, iBGP over a GE between them. If one toasts you'll only lose half your routes for 1s-ish, or however long you set your OSPF keepalives. While you're at it, add extra fans and run the edge systems off solid state disks or CF cards. Or, buy $real hardware. -Jack Carrozzo On Thu, Mar 4, 2010 at 12:17 PM, Alex Thurlow <alex@blastro.com> wrote: > Let me preface this by saying that I'm not a full time network admin, but > we're a small company and I'm the only one handling this.
