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?

Hi, this is not a scientific answer, but since no one else replied, here is what I found a while ago... When I installed Freebsd 6, i did a lot of reseach/posting and found out that there is no way freebsd will handle multiple routes to the same destination I was hoping to have two default routes for redundancy (and if possible, load balancing) I never heard of a kernel patch, and if there was one, I wouldn't feel confident with it (just my opinion) I then went with a routing package (there is zebra and quagga) which kinda did the trick. (I used quagga since I had some problem setting up zebra from the ports). It works fine but adds a level of routing that could have been handled by the kernel I guess.
