RE: Multiple routes to same destination?
You are right, Zebra will keep only one route in freebsd routing table since Freebsd cannot handle more. At Least zebra will change that route in the routing table if it detects some kind of network topology change (depending on the routing protocol) Best I've been able to reach. I really don't know why freebsd still doesnt support that Linux and even windows supports that :) ~~ Ian Lord MSD Informatique 1711 Montée Major Terrebonne (Québec) J7M 1E6 Tél: (514) 776-MSDI - (514) 776-6734 Sans Frais: 1(877) 776-MSDI - 1(877) 776-6734 http://www.msdi.ca -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Webster, Andrew Sent: 8 février 2006 09:11 To: Ian Lord; freebsd-questions@freebsd.org Subject: RE: Multiple routes to same destination?
