...pply the content of route-eth0 to take down the routes listed and ifup-route brings up routes based on route- So what ends up is that the old routes never go away, just new routes added. ifdown eth0; ifup eth0 works, but is a bit heavy-handed for only changing routes. So how do I clear out the routing table and have it rebuilt based on ifcfg-eth0 and route-eth0 without bouncing the interface completely?

Hello all, Tomas Bonnedahl and I recently corresponded about a rather odd behaviour with routes in ancillary routing tables. We both receive a "Network is unreachable" error when we try to add gatewayed routes to ancillary tables and the main routing table does not contain an entry for the gateway IP. It seems that unless a route to the gateway IP exists in the main routing table, I cannot add a route...

This run was done this AM on my linux box, and older 32 bit Dell optiplex (core 2 duo). The failure message is at the very end. (It's due to be replaced in a couple of weeks.) The sequence of steps was svn up tools/rsync-recommended ./configure make make check-all |& tee zzz Terry T. Result of ./config R is now configured for i686-pc-linux-gnu Source directory: .

Hi list, I''m trying to setup a Linux box with a complicated source routing and could use a hand from you. The box has 4 NICs and lots of VLANs attached. It is a firewall and router in the following scenario: (obs: IP addresses have being changed for security purposes) - eth0 holds the default route (GW: 200.1.0.1, Firewall: 200.1.0.2); - The box is routing and someti...

...is labeled as status ''works''. I have tunnels back and forth across the internet, using ''nth'' to balance packets between different public networks (over the tunnels). I need to access some networks over two tunnels, and some network over three tunnels. I cant get routing working correctly when combinations of two and three tunnels are involved. *now for the more techincal explanation* Tunnel Server 1 (kernel 2.4.28, iptables 1.2.11 with nth and route) Network A is delivered over three tunnels to Tunnel Client A (works fine) Network B is delivered over three tunnels...

Hi, Is it possible to use more than one default route? I believe yes. Any comments on them. If I use more than one, where will the trafficc be diverted from?

Greetings routing folks, I want to use the netmask 255.255.255.255 to insulate (not quite isolate) machines on a shared subnet from each other. This works just fine on win XP, but Linux iproute will not acccept the gateway address in one step -- neither on the command line nor via DHCP: Here''s the in...

...going on in fib_hash.c, fib_rules.c, and route.c, I have not succeeded to my satisfaction, hence my post. I''m trying to document the general process of route selection, and have come up with the following overview. Could somebody point out any flaws in my understanding of the use of the routing cache during route selection and the route selection process? Starting point: packet enters the routing stage. - Attempt a lookup in the routing cache according to the following: + destination address + source address + type of service (tos) + fwmark (fwmark) + interface o...
